Please log in for more thread options Hi Guys, I will attempt to explain this problem as best I can. I recently got high speed access to the net via a wireless dish. The dish has some client equipment in it and is connected to my PC via wired Ethernet. My PC has been assigned a static IP for the network, and because we are behind a router its not a real world IP. The problem is that rnadomly I loose my connection to the internet. I still show a connection on the LAN indictaors on the status bar. Now I find that if I click Repair on the context menu for that connection everything is fine again. This can happen a few times a day. The service provider swears its nothing at his end, and the fact that I have to repair to fix it kinda supports this theory. I dont know much about the gear but that its Trango. I am on XP SP2 with the latest IE7. Anyone able to shed any light pease? Thanks -AL | |||||||||||||||||||||||||||||||||||||||||||||||||||||||

I am on XP SP2 with the latest IE7. The first thing to try is to disable power management on your computer's network adapter. Go to Control Panel>System>Hardware>Device Manager. Expand
the network devices category and find your ethernet adapter. Double-click
it to get its Properties. Click on the Power Management tab and uncheck the box that says "allow Windows to turn off this device when not in use". See if that helps and if it does not, then please post back with a bit more detail about your particular computer's hardware and its virus/malware status.

window and that the ethernet device on your unspecified model computer
does not have a power save feature. However, the question remains, why does it work for you. My guess is that you can get the exact same effect by simply unplugging the ethernet cable, waiting a few seconds, and plugging it back in. Does this also fix the problem? >This can happen a few times a day.
>The service provider swears its nothing at his end, - How many times is "a few"? Numbers please. - Is there any pattern to the outages? For example, does it only happen during normal eating times, when microwave ovens tend to be operating? Is it different on weekends? - Are you using the computer when it dies, or have you left it idle for a long while? - You may have lost the internet, but have you checked if you've lost your ISP's gateway? Determine the gateway IP address by running: start -> run -> cmd <enter>
ipconfig
Then try pinging the gateway when it's working, and when it dies: ping ip_address_of_gateway If it does NOT work when it goes dead, you have lost your wireless connection to the WISP. - Does it *REQUIRE* that the connection be repaired, or does it fix itself if you wait long enough? How long? Use: start -> run -> cmd <enter>
ping -t ip_address_of_gateway
and watch the error messages. When normal results return, it's back to working. If the downtime is approximately that of cooking a microwave dinner, I think we have the culprit. There also ping tools which will help run this test continuously: <http://www.tools4ever.com/products/free/freeping/>

>supports this theory. No, it doesn't. For example, if the WISP's DNS servers were screwed up and not responding, it would appear that you can't surf the internet, while all that's happening is that you can't resolve the domain names into IP addresses. Try obtaining the IP address of a popular web site and using that instead of the name to see what happens when it does down. To get the IP address, run something like: ping www.yahoo.com then try the resultant IP address in the form: http://66.94.234.13 If your wireless ISP is using some kind of DNS load balancing scheme, or you have one of the three possible DNS servers typed in wrong, you might see some problems. It may also be something as simple as the time delay required to repair the connection if the outages are fairly short in duration. >I dont know much about the gear but that its
>Trango. I am on XP SP2 with the latest IE7. Trango has a support forum. I suggest you ask about signal strength and interference problems. <http://www.trangobroadband.com/forum/default.aspx>
If the diagnostics returns that you have a marginal signal to your
WISP, you may need to tinker with the antenna, or do some repositioning to avoid interference. >Anyone able to shed any light pease?
If shedding light is anything like shedding fur on a dawg, I don't think you will want it. My guess(tm) is that if you're absolutely sure your XP setup is correct, that your signal is good and strong, and that you have line of sight to your WISP, I would then look into interference problems. A "few" times per day sounds like a microwave oven. It does not need to be yours as anything along the line of sight (and beyond) to the ISP will cause problems. See the FAQ at: <http://wireless.wikia.com/wiki/Wi-Fi#Interference>
for a laundry list of possible culprits.

Gee - Thanks for all the great suggestions so far!! I have turned off power management for the adapter as instructed, but as i can not re[licate the problem at will, I will just have to wait and see. > Does it also have a statically defined gateway IP?

I am running an Asus A8N32-SLI Deluxe motherboard with a AMD Athlon64 2.2Ghz 3500+ chip. The twin onboard (motherboard) ethernet adapters are Marvel Yukon 88E8053 Gigabit Ethernet Controllers. Under power management for these adapters I have unchecked the setting "Allow the computer to turn off this device to save power" >

Thats a interesting point - because it has been happening in the mornings, but also happens overnight (I am not on my computer but my MSN is logged out suggesting a loss of connectivity) > - Are you using the computer when it dies, or have you left it idle

I thought about that too - I have had my HiJackThis log checked over at CastleCops- and I am clean. Also running Ewido and Kaspersky - all clean.
