Greetings all... I have had two laptops connected to a Linksys WRT54G wireless router for about a year. Recently, a laptop went down and I added a desktop PC. The laptop is XP SP2 with a Orinoco WaveLAN Gold 802.11b PCMCIA wifi card. The desktop is XP SP2 with a Belkin 11Mbps Wireless Desktop PCI Adapter (F5D6001 V.2). Today, they started having issues with connectivity. The main problem machine is the desktop. Usually, they both connect fine and reain with high radio signal and stay at 11Mbps. Both are 802.11b adapters. What's happening is the desktop will drop the signal completely and when it does, the connectivity of the laptop suffers, by lowering to 6mbps or even 1Mbps. Then after a minute or so, the desktop will come back up and the laptop will resume it's optimal connection. The router is not in my apt. It is nearby and is run by the complex. Up until today, I could log into the 192.168.1.1 setup screen with the default password of admin and login left blank. It appears it has been changed by whoever. I never had any reason to go into the setup screen and screw with everything, but every now and then I would go in and reset the channel due to interference in the area from other 2.4 ghz devices... What is causing the fluctuations in the connection? Is it MAC filtering of some sort? Or a proxy? There is no WEP and I don't believe any type of WPA setup by the apt complex. I just want a reliable connection to the two machines. The disconnect/reconnect happens every 30 seconds to minute. Is there some uber haxor way to get the login/password once it's been changed?;f Anyone have any ideas on what to do? Here is a screenshot of the laptops ipconfig screen when connected properly: Here is a shot of the same from the problem desktop machine when the connection works: Let me know what other info you might need to help me out. Thanks.
