I have a high-speed connection with a Nortel 1 Meg modem, connected to a SMC Barricade Wireless router. I have two computers connected via cable to the router and everything worked flawlessly all summer. One of the computers had a Lindows OS and it too connected with ease at the first attempt. Later I bought a Belkin wireless USB adapter and attached it to the Win98/XP machine and it too functioned well.

Just last week, I hooked my daughter's Laptop (HP Pavilion zt 1210) with WinXP Home and the problems started very soon. First I noticed when Laptop was connected, I couldn't access even my ISP. Everything ground to a halt. However, as soon as unplugged Ethernet cable from the Laptop everything was fine. I noticed that The Loop TX/RX light flashes red continuously all the time when the Laptop is connected. This light presumably indicates that the modem is receiving data from the computer.

I checked all the programs in the Laptop and nothing seems suspicious. Even the ping command to the router loses 50% data and at times reports 0% loss. The Laptop and the router are in the same room. I have had occasional connection to the net via the Laptop but most of the time, it hangs. I have downloaded WinsockXPFix utility and the problem still remains. The red light on the modem keeps flashing, even when the Laptop is not logged in with any user, just the power is turned on and the blank login screen is displaying. I get the same problem whether I use the cable connection or the Belkin wireless adapter.

Everything was working until last week. My daughter's Laptop worked flawlessly all summer both with a wired and a wireless connection. Hoever, my daughter had taken her computer to Toronto last month and had installed Sympatico Access manager as she was trying to get the sympatico service via a Bell supplied router. She could never get the connection going and so could not have had any virus infection since the time the computer was working in Ottawa.

Any suggestion or help would be really appreciated.

Thanks
 
on the linux machine do the following:

tcpdump eth0

and then plug in the laptop and see what network traffic you get - it'll be a starting point for suggestions.

You can probably use 'netmon' on the XP machine if you prefer. Either way you want to know what the laptop is pushing onto the network.

1. Bad cable; or,
2. Autonegotiation failure. Try forcing the speed and Duplex setting needed rather than have the network adapter try and autonegotiate these settings; and/or,
3. Check the MTU settings. The Sympatico attempted installation may have set these completely inappropriately for your home network. This would explain the fragmented frames issues, and other things.
