Hey Jeff,
Thanks a lot for your help, sorry for being ambigious before, and
providing WRONG Information..SORRY! :(
My Access Point is not BEFW11S4 its BEFW11S4, a Wireless-B Broadband
router! (which I think can be used as an access point though)
1. Both the access point and the router are using different channels,
the WRTP54G is using Wireless Channel 9 and the BEFW11S4 uses Channel
10 (2.462 Ghz). However, both have the same SSID, I dont know how bad
that will be, but I heard that if you are using one as an access point,
then they both should have the same SSID.
As far as the distance between the two routers is concerned, they are
about a 70-100 ft away, and on different floors, and since I'm in
India, there are concrete walls and not wood.
There is however, a cordless phone next to the BEFW11S4, it works on
5.8Ghz though, so I doubt that would be giving me the problem.
2. About internet connectivity speed, I downloaded iperf, but when I do
iperf -c 192.168.15.2 ; it throws me a connect failed: connection
refused message, am I suppsed to do it any differently?
3. When I ping my BEFW11S4, at first it gave me 6ms, and then after
repeated pinging it dropped to 1 ms

4. About the hardware, my PC is a Fujitsu Lifebook S7010D, which has
the Atheros A/B/G inbuilt wireless card, hardware profile is pretty
decent with centrino and 1 gb RAM.
The router is BEFW11S4 V4, with 1.50 as the Linksys Firmware.
5. My internet connection isnt like amazing, but its a 512Kbps DSL
connection, and it seems to behave fine when I'm connected to the
WRTP54G (Vonage) wirelessly or wired-ly. And gives me good speeds as
such.
6. COnnecting to the BEFW11S4 wirelessly, I get excellent connectivity
and it shows 11Mbps as my connectivity speed. Is BEFW11S4 a Wireless B
router?
7. Another strange thing, is that even though pinging 192.168.15.2
gives me 1ms after a point, there are times when I'm navigating the
admin setup using IE, and it starts showing me Page Not Found, which
would technically mean it was not able to find
http://192.168.15.2 ,
strange.
Thanks for all your help though!
