I have been having problems with my wireless for sometime now...SO I replaced my Router (to: TP-Link TR-TL841ND N) and wireless card ( TP-Link TL-WN821N). I also replaced my motorola modem (SB5101N). I have a old Linksys BEFSR41 4 port wired router to give me enough ports for all my stuff. both TP-Links support QSS ( dont know how to use it). Memory use is erratic with a 25-50MB swings in a fairly stable wave. Laptop is running XP Pro, 1GB ram and 1GH processor.
My laptop will be at 2-5% CPU until I plug in my wireless card. It then shots to 95-100% usage. The main culprits are system and Task manager or IE and sysem when I have a IE window open.
I also am having my wireless dropped. It will usually recover without intervention.
I have the router in a location that is free from metal in a 5' radius. No metal beams in the house...just standard construction.
I have run Dr. Web, MBAM, SAS and ATF cleaner. All are clean.
this relatively new issue on an established home network. I have run the new router disk on only 1 of the 4 computers that connect to it...I did run he wireless disk on the laptop...not sure if I updated the laptop with the newest driver for the wireless card. I have the newest firmware for the router but have not installed it yet
In a related issue ( I will create a new thread to address that issue once I have this one cleared up) I randomly loose internect connect on 3 wired PC's or cant connect a random website. right now 1 of the 3 has lost total connection even with a static IP. I have changed the cable and router port with a know good one but not the NIC card. It worked fine until a few days ago. Alot of the time repair doesnt work and I have to take the network down and reboot everything. This doesnt work for the one that wont connect. I have not run full scan on Dr Web but everything else listed above.
Let also say I went to a local hotspot and had no problems with CPU usage or connectivity for about 30min...My Ipod touch also freezes when connected to the home network but not others...
