How can we tell from a WiFi card spec whether the NIC is 2.4GHz or 5GHz, or both?

I am out of this thread. You are impossible. When e say it is dual band it is. If you can't believe why don't you ask HP? So much hassle buying a laptop.

I apologize and agree. I had posted a screen shot of all the information that HP provides: But that's all I have.

The problem is, if I look at a DELL or Toshiba or Lenovo laptop, I'll still have the SAME PROBLEM of figuring out whether it has 5GHz or 2.4GHz or both, from the specs.

So, it behooves us to be able to read the specs.

From what Jeff said, all I can tell is (is this correct?):

802.11 a ==> 5GHz only 802.11 b ==> 2.4GHz only 802.11 g ==> 2.4GHz only 802.11 n ==> 2.4GHz only? 802.11 ac ==> 5GHz only

Basically, if it has an "a" in the description, then it's 5GHz. Otherwise, it's 2.4GHz.

Since this thread is really about INTERPRETING specs, is this interpretation correct?

  1. Intel 7265 BGN + Bluetooth Version 4.0 Would it be safe to assume this has *only* 2.4GHz?
  2. Intel 7265 AC/B/G/N Dual Band Wireless + Bluetooth Version 4.0 Is it safe to assume this has *both* 2.4GHz & 5GHz?

So, if 'n' can run on either, when a spec only says 'b/g/n', how do you know whether the 'n' is 2.4GHz or 5GHz?

If you don't believe the numbers, then what do you believe?

Nope. Office 2007 will run on Win 10: Grab Belarc Advisor, run it on the XP machine, and PRINT the results. Somewhere in there, it will have the various serial numbers needed for the installation. If the ancient XP machine crashes without a backup or a list of serial numbers, she will not be able to reinstall Office

2007 on a new machine:

Right. With only one machine, Office 365 doesn't make economic sense. I was thinking of a skool, not an individual user. I still think the various alternatives (Google Office, LibreOffice, etc) are worth investigating.

Good luck.

It tells me that HP marketing is clueless. The assumption is that anything that does "ac" will also do the lesser protocol of "a". Since "ac" only works on 5GHz, and nobody today makes a 5GHz only radio, it's a fair assumption that anything with "ac" will be dual band. However, that's an assumption. I tried to find the Intel card used in the 15z and failed. You'll probably have to ask HP pre-sales, this I predict will be clueless. You might try the HP support forums.

Nope. It should be: 802.11 a ==> 5GHz only 802.11 b ==> 2.4GHz only 802.11 g ==> 2.4GHz only 802.11 n ==> 2.4GHz or 5GHz 5GHz only

Yes, but the "a" and "ac" are a concidence. The IEEE 802.11 committee(s) ran out of letters when they hit "z", so the started using two letter suffixes as in "as", "ab", "ac", etc. There fact that "a" and "ac" are both "5GHz only" is purely coincidental and should not be relied upon to determine if something operates on 5GHz.

As I mentioned before, if it does "ac", it should be able to do "a". Nobody makes a 5GHz only radio these days, so if it does 5GHz in any form, it should also be able to do 2.4GHz. However, these are logical deduction and assumptions which should not be relied upon. To be sure, you need to pry the Intel product number out of HP and lookup the specs on the Intel web site, which should have a better description of the products capabilities.

Notice that "b" and "g" are ONLY 2.4GHz - but - notice that either "n" or "ac" is also 5GHz." 09/06/2015 08:57:20PM Agent (Vann): "Thanks!" 09/06/2015 08:57:32PM Agent (Vann): "Let me check that." 09/06/2015 08:59:32PM Ewald Bohm: "Hi Vann So, we still don't have the answer, since clearly both "n" and "ac" can do 2.4GHz and 5GHz - the only difference is that "n" can do either one at a time while "ac" does both at the same time - but that's not my question. My question is whether th" &nbsp e "n" and "ac" cards from HP for this laptop are 2.4GHz or 5GHz or both. Thanks for "owning" this issue to the conclusion - since - it's actually an easy question - for someone who has the spec to answer. In fact, I fault HP for not putting that answer on &nbsp the web site since it's a CRITICAL question to ask! 09/06/2015 09:00:18PM Agent (Vann): "Ewald, I see where you are coming from." 09/06/2015 09:00:53PM Agent (Vann): "I even sent a quick email to the marketing department and web content team to put a brief pertinent description of each wi-fi options." 09/06/2015 09:04:48PM Ewald Bohm: "Hi Vann, As I had said, I was a customer-support manager for twenty years and I found only about 10% of the support team would take the time to solve long-term problems such as missing information in a web page; therefore, I do appreciate that you are in" &nbsp the top 10% for "owning" the problem, and I appreciate that. I'm still not sure though, whether the specific cards available for this laptop have "both" 2.4GHz and 5GHz bands, since we have ascertained that "n" can be either (just not at the same time), w &nbsp hile "ac" also can be either (but if it has both, it can do both at the same time). So, the FREQUENCY BAND is a critical piece of data that a person needs to figure out if their laptop will connect to the "n" or "ac" 2.4GHz or 5GHz bands. 09/06/2015 09:04:55PM Agent (Vann): "Ewald, as far as what I understood in my readings here. You need a dual band that can support both 2.5 and 5 Ghz." 09/06/2015 09:05:26PM Agent (Vann): "This is what you need WLAN 802.11 ac 2x2 ." 09/06/2015 09:05:35PM Ewald Bohm: "Hi Vann, Yes. I will ONLY BUY a dual-band card. I am just trying to figure out which card(s) that fit that laptop are dual band." 09/06/2015 09:05:50PM Ewald Bohm: "Note: It's 2.4GHz and not 2.5GHz." 09/06/2015 09:06:10PM Agent (Vann): "Sorry for the typo error." 09/06/2015 09:06:18PM Agent (Vann): "So you are saying that your router has a dual band?" 09/06/2015 09:08:41PM Ewald Bohm: "HI Vann, I know MANY (most) "ac" cards will be dual band. But, remember, an "ac" card can also be one or the other. So, I am just trying to CONFIRM whether the "n" and "ac" cards you offer actually make use of both bands. (I know that the "n" can make use" &nbsp of either band, and so can the "ac", with the only difference not mattering to this question that "ac" can do it simultaneously). But, "ac" can't do it simultaneously if it doesn't have both bands, and "n" cards can be of three types (1) only 2.4, (2) o &nbsp nly 5Ghz, or (3) both 2.4GHz and 5GHz. As for my router, it is dual band (both 2.4GHz and 5Ghz) and it is an AC1750. 09/06/2015 09:14:10PM Ewald Bohm: "Hi Vann The 802.11n spec allows up to 4 transmit and four receive antennas (802.11n supports up to 4x4), so, again, just knowing it's 2x2 or 4x4 does not tell me what the bands are." 09/06/2015 09:17:33PM Agent (Vann): "Ewald, I am sorry if I kept you waiting." 09/06/2015 09:17:40PM Ewald Bohm: "I'm here ..." 09/06/2015 09:18:06PM Agent (Vann): "This is overly complicated and it would be better you consult our product expert." 09/06/2015 09:18:23PM Agent (Vann): "As far as I know that if it has a 1x1 that is a single band which can support up to 2.4ghz/" 09/06/2015 09:19:36PM Ewald Bohm: "The 1x1 means one (dedicated) transmit antenna and 1 (dedicated) receive antenna; the antenna itself can be any frequency (either 2.4GHz or 5GHz) but almost all the time, it is 2.4GHz (I agree) but it does not have to be since the 1x1 is indicating the de" &nbsp dicated "channels" and NOT the frequency band! 09/06/2015 09:20:46PM Agent (Vann): "It looks you've done more research on this and you get a lot of understanding how these things work." 09/06/2015 09:21:36PM Agent (Vann): "Can you check this link

You have to realize what you're saying, & that your suggestion can't work.

If you were suggesting to "me" to use openoffice or staroffice or libreoffice or framemaker or numbers-pages-keynote or polaris office or kingston office or wps office or any number of freeware office look-alike apps, then your suggestion might actually make a lot of sense.

But, you can't take the average extremely non-technical grade-school teacher, and seriously suggest they use a free office-like equivalent, when they have enough trouble just getting used to the ribbon changing from one Microsoft office version to another.

They complain when they have to open an office 2013 doc in office 2007, and they fail at that, half the time, without help.

They can't even print something as simples as a protected PDF without my help.

So, if you're suggesting that free office-look-alikes are "equivalent" to office for such a person, then you fundamentally don't understand people.

It's just not gonna happen.

You missed the point.

I'm trying to *recommend* a laptop for a teacher who is not technical. I started at Costco, but the Costco laptop wasn't dual band. I went to the HP site and can't figure out if it's dual band.

If it's dual band, I'll recommend the teacher buys it. If not, I will choose another laptop.

I don't actually care what laptop she gets. I'm just trying to help her.

The laptop has to be about the right size & shape. It has to be within her price range (around $500 out the door). It has to have MS Office on it. It has to be Windows.

Everything else, she's leaving up to me. One thing I'm requiring is dual band 2.4GHz & 5GHz simultaneously (with backward compatibility).

All I'm trying to find out is if this HP 15z laptop is dual band. It's amazingly difficult to find this out.

I'm online right now with a supposedly-special HP customer support sales hotline (888-999-4747), and they STILL don't know the answer.

Thank you Jeff for clarifying this spec:

After a half hour on three separate HP calls, I learned something (I think) that nobody told me yet...

  1. HP Tech Support 888-222-0029
  2. Advanced HP Tech Support 866-221-4553
  3. HP Shopping Team 888-999-4747

HP: They first told me the ac card was just ac. ME: I told them that this was unlikely, so I asked them to doublecheck.

HP: After a long wait, they told me the "ac" card was backwards compatible, but it was only 5GHz. ME: I told them that was impossible.

HP: Then, after another long wait, they told me it was NOT dual band, but that it had both bands. ME: I told them that this confused me, and I asked them to clarify.

HP: Finally, they came back and said that the "ac" card was backwards compatible, so that it had two frequencies, but they don't operate at the same time, so it's not dual band. ME: I said thank you but I would like to ask you, Jeff, to clarify.

Does that HP answer make sense? The "ac" card is backwards compatible, so, it has both frequencies, but it doesn't do both frequencies at the same time?

What does that really mean?

This should be correct, by now, where I appreciate Jeff's patience:

802.11 a ==> 5GHz only 802.11 b ==> 2.4GHz only 802.11 g ==> 2.4GHz only 802.11 n ==> 2.4GHz or 5GHz (or both?) 802.11 ac ==> 5GHz only

Jeff: Notice the question mark in the "n" spec. Is "n" always just *either* frequency (i.e., one or the other). Or can "n" be either one or the other or *both* frequencies?

Ewald B?hm

Jeff. You are correct. But you were thinking differently than I was.

You were thinking of bringing the (winxp desktop) 2007 license upward to the new (win10 laptop), and I discounted that out of hand.

This is a hand-me-down desktop that someone else didn't want, so they gave it to this teacher, many years ago. It came with zero discs!

But that wouldn't stop you or me.

If it were you or me, we'd use Belarc to find the original office product key (or serial number, I forget which) and we'd then find the Office 2007 download ISO hidden deeply on the Microsoft web site - and we'd download that Microsoft-provided ISO, perhaps burn it to optical disc for re-use, and we'd simply install Office 2007 on the new laptop from that ISO, and we'd bring over the old key that we unearthed using Belarc Advisor.

In the end, you or I would have Office 2007 running on their one (winXP) desktop and their one new (win10) laptop, which is within the license constraints (I believe).

But that ain't gonna happen with these people. They are not technical. They can't handle the complexity.

Plus, it's time they moved into the new century, so, if they stick with Office 2007 (which they continue to call "Word 2007", not realizing there are multiple office apps), they will eventually have problems reading Office 2013 documents.

So, it's time they got a new Microsoft Office suite.

Since they will *keep* the WinXP desktop with Office 2007 on it, all we're looking at is a *single* license of Office 2013 (which they continue to call "Word 2013", which means they're not using Outlook).

So, the price comparison is the following:

  1. Pay 0 per year for Office 365 for the rest of their lives, or,
  2. Pay 0 once, for Office 2013 H&S for the one laptop.

To me, unless I missed a step, it's a no brainer.

See my post of a few seconds ago where I reported the results of three sets of phone calls to HP today.

I have asked Jeff to clarify what they told me, but here's the scoop.

In the end, they said, that the "ac" card was backwards compatible, so, that meant that the ac card contained *both* frequencies, but the caveat was that the "ac" card was *not* dual band.

When I asked them to clarify, they said it doesn't work on both frequencies at the same time.

What does that really mean? Is having two bands dual band, or not?

Ewald B?hm

After my conversation with HP today, I found out that their "ac" card has both 2.4GHz and 5GHz because it is backward compatible, but they said that backwards-compatible-ac-card is *not* a "dual band" card.

Apparently they defined "dual band" in a specific way, that excludes the fact that it has "two" bands.

Finding Office 2007 replacement CD's is trivial. Hint: BitTorrent.

If it were purchased online from the Microsoft site, and you have the magic serial number, you can download a replacement ISO image.

Yep. I vaguely recall that Office 2007 works on 2 machines. Not sure.

I'm technical and I hate complexity. Teachers have students, which just love to help with such things. Some of the teenage hackers are quite knowledgeable and have impressive experience in the dark arts of computing. Ask the students for help.

Maybe, but that hasn't been my experience. I can read most anything produced by Office 2007, 2010, and 2013 with Office 2003 and the MS Compatibility Pack: However, if there's a problem, I just ask the author to Save As: Word

97 format.

The way you can tell when it's time to upgrade is when you can't get the work done or that it's painful to use. I have no problems reading or writing with Office 2003 and various file format converters. I find Office 2007/2010 to be tedious, awkward, clumsy, and not much of an improvement over Office 2003. In other words, a step backwards. If your really think it's time for a change, I suggest they step into the (disk) space age, and take the great leap forward to Cloud Computing with a Chromebook and Google Office.

Outlooks is dead anyway because Windoze 10 includes mail and calendar apps.

  1. Pay nothing and use Google Office, LibreOffice, or similar free alternatives.

Well, you're right about not using your brain. What I find odd is that your primary reason to spend the money is the inability or unwillingness of a teacher to learn something new. I've seen this phenomenon with teachers in the past, where the monotonous repetition of cramming facts into students heads eventually leads to intellectual ossification. Even in computing, I guess perpetual reptition of the same mistakes is considered a good reason not to change one's habits. Personally, I find the logic disgusting, but I promised to improve my diplomacy and won't push the point any further.

Here's what I suggest:

  1. Have the teacher beg, borrow, buy, or steal a Chromebook. I have several Acer products and find them quite good and cheap. The various C720 models are what I use and like (also to run Linux). Figure about 0 to 5 refurbished.
  2. Have one or more of the teachers students setup the Chromebook so that it's ready to use. The learning curve is not very steep or long, but since that seems to be an issue here, faster is better.
  3. Have the teacher learn to user various Cloud Computing services, such as Google Cloud, MS Skydrive/OneDrive, etc. Also have the teacher learn to run apps inside the browser. If MS Word is required, then MS has the real thing available:
  4. If the teacher makes it this far, the rest should be obvious.

Please note that I did not suggest that you call support. I suggested you call pre-sales support (shopping team or something similar) and ask what model Intel wireless card is the "ac" device.

Sorta, if I read between the lines.

"ac" is always backwards compatible to "a". It has to be. Short lecture follows:

If you force the wireless router (not the client radio in the laptop) to do only "ac", then the maximum from router to laptop will be rather short. Basically, at a fixed power level, you trade range for speed. "ac" is all about speed, so the range decreases when it's used. If the BER (bit error rate) increases above some pre-programmed level, the router in "ac" mode will slow down, eventually going to the slowest "ac" mode speed. To go slower than that, it would need to revert to some "n" mode. Once the router slows down to the slowest "n" mode, it will need to go to ordinary "a" mode. If it didn't go: ac -> n -> a the wireless connection would not work more than a few feet in "ac" mode. Therefore, to obtain tolerable performance at reasonable ranges, the wireless devices need to support all the modes down to "a".

There is one exception. 802.11b is so disgustingly slow that the

802.11n spec (and others) demand that 802.11b be disabled if 802.11n is active.

End of lecture section (for now). Quiz to follow.

Now, on to the "dual band" problem. The issue of "simultaneous dual band" is more of a router problem than a client radio problem. The usual idea is that you can have different devices use different bands as required. To do this requires simultaneous dual band in the router, but not in the laptop client radio. For example, I've setup Roku wireless media player boxes to use 5GHz, while the laptops and tablets are all on 2.4 Ghz. I've also done the reverse, when there's so much screaming media traffic on 2.4Ghz that the only band that's usable is 5GHz. Simultaneous dual band is (in my opinion) a requirement for wireless routers and access points. However, for laptops, tablets, and wireless client radios, it's only useful for marketing types that want to advertise higher speeds. There are protocols for bonding both the

2.4 and 5GHz channels between a laptop and a router in order to get higher download speeds. You're not going to see that on a $350 laptop and don't need it anyway. Therefore, the HP phone person was right that it's one band at a time, not both simultaneously.

Incidentally, the Bluetooth device shares the same radio as the 2.4GHz wi-fi section and are setup to alternate their operation so as to not mutually interfere with each other.

It means you've educated the HP phone support person. Somehow, I don't think that was your intent.

I just hate it when you ask consistently good questions. I feel obligated to answer when I would rather roll over and die from spending most of the Labor Day holiday running wires under a house. I'm getting too old for this kind of work.

Operating on both frequencies at the same time is called "simultaneous dual band". This is commonly found in wireless routers and wireless access points, but not in wireless client radios, like the one in your prospective HP laptop. The wireless router needs simultaneous dual band because it might have two different users, connected at the same time, each on a different band. Were the radio NOT simultaneous dual band, the traffic bandwidth would be roughly cut in half because the wireless router radio would need to switch back and forth between the two users. However, with simultaneous dual band, it could service both users at the same time without any loss of bandwidth.

For completeness, there is the original 802.11 (with no suffix) that is also on 2.4GHz. IIRC, maximum speed for that is 2Mbps.

Yep, however those were incorporated into the 802.11b specification. The two slowest speeds of 1 and 2 Mbit/sec became part of 802.11b when

5.5 and 11 Mbits/sec were added. Besides DSSS (direct sequence spread spectrum) there were also a few FHSS (frequency hopping spread spectrum) promoted by Raytheon, Breezecom (Alviron), and TI. However, you won't see these in modern equipment, unless you include BlueGoof, which is FHSS.
