WifiQ: Why does my laptop disconnect from my WAP?
posted by SirStan to Computers & Internet (7 answers total)
I have the following:
Dell Inspiron B130 (xp)
Dell Latitude D620 w/ all wifi power management turned off. (xp) - Intel Pro 3945ABG
Desktop w/ DLink WIFI w/ ubuntu
Linksys Business Wireless AP
Linksys WRT54G (V3?) running DD-WRT, underblocked, underpowered.
Buffalo Something something running DD-WRT Generic
The issue is my laptop will disconnect from the WRT54G randomly. Initially I thought it was a power, channel, or overheating issue, but the desktop *never* loses connection, nor does the B130. It is only my D620. There were some articles related to power management causing the Intel Pro wireless to lsoe signal, but I have disabled that.
The issue only occurs on the WRT54G. My laptop stays connected 24/7 to the junk Linksys business wireless router, and the BUffalo running the same firmware.
The desktop and B130 stay connected to all three, but the Linksys business router seems underpowered, and the desktop will lose signal strength (it averages ~20%, but if the cat lays next to the TV, it drops). I would like to use the WRT54G and not pay $60 for a new Buffalo (this one is stolen from work), but the Buffalo seems to fix the problem.
Why would two waps, same firmware, similar hardware, similar laptops exhibit this problem? I had pings running on all three machines, and the b130/desktop never seem to go above 2ms, while the D620 dropped signal half way through the night. It even occurs while on AC, and I am actively using it. Reconnecting doesnt' fix it, I usually need to disable and reenable the device in Network control panel.
