text: why is my computer erratically losing connection with my wireless router, it works with my 2nd computer? the connection repair option on windows xp sometimes works, sometimes not. my router is linksys, about 2 years old. i have run all of my anti-virus, anti spyware/adware, clamwin and norton... i have run defrag and diskchk. i have rebooted several times. the connection to the router ranges from 54mbs, down to 5mbs. the signal quality ranges from excellent down to very low. and the status is connected or not. i have not been able to isolate the specific problem as to hardware feature or software feature. unless someone can provide an answer, a clue or a new direction, i will go with the the wireless network card, about 2 years old. i have verified that the card and conections are not loose. all help greatly appreciated! this happens when you have a cordless phone running at 2.4 ghz or a microwave device.mostly the reason is the cordless phone,which is the same frequency in which your linksys wireles router operates .some solutions that might help  try to turn off the the cordless phone including the base unit , and after a minute try to check the signal strength .   try to change the routers wireless channel to 6 or 12  if this does not help you might have to contact the cordless vendor and tell them to change the frequency of your cordless phone to any other frequency other than 2.4 ghz.  if you need any further help please post your email id  regards, amrith former senior escalation engineer (linksys , microsoft)
