Do older routers have speed limitations? not work with powerboost? riggor9999 03-04-09

All -  I have an interesting question .....

I have a BEFSR11 router that I have not been using for a while (this has
last firmware available - from 2004).  I am a Comcast customer and I am
using a BEFCMU10 DOCSIS 1.1 cable modem.

I was using a Vonage / Motorola VT2442 router but I needed more flexibility
with firewall rules - so I put back my BEFSR11 in place, and put the VT2442
behind the BEFSR11 (via my gigabit switch) and the only thing connected to
the VT2442 is the phone.  Phone works fine - no issues.

Cable modem <---> BEFSR11 <---> 24 port gigabit switch <--->  pcs,
printers, VT2442, blu-ray player, wireless access points, wii, itouch, etc.

Since I made the change - I noticed my download speeds have slowed down. I
have also gone to the variety of speed test sites and what I basically see
is that powerboost is not working or not there.

I tried these sites - which always show download speeds that include the
effects of powerboost - but now - I always get 6mb down and 3mb up.

I looked through the Linksys support sites and various forums but could not
find the answer .... Is there a speed limit to the BEFSR11? Or more
specifically - do older routers not work with Powerboost?

I have not put anything back they way it was - because I need the better /
more flexible firewall rules that the BEFSR11 has and the VT2442 does not.

Thx

I'm thinking the WAN port is 10base-T, which would pretty much explain the

That is exactly it ...  I did not think to check - ugh ...

WAN: 10Mbps (10BaseT Ethernet)

LAN: 10Mbps (10BaseT Ethernet) or 100Mbps (100BaseTX Fast Ethernet)

  That wouldn't limit you to 6 Mb, though. I'm gonna guess that that
problem is about Powerboost needing DOCSIS 1.1+.

It was fine with the same cable modem and the motorola vt2442 router.  I am
guessing that since the wan interface is only 10mb ... powerboost senses the
limitation and stops "boosting" so it falls back to the standard 6mb.
