Ive owned the Linksys WCG200 for 2 years now and just started have issues...and I FINALLY found the problem: For wireless connections only, its making my wireless client renew ip's almost every 5 minutes. At first I thought it was just my laptop....but my wifes laptop does the same thing. Ive noticed other posts on here about the same issue, and just wanted to make sure that I have no way to fix this....other than purchasing a wireless router, turning off the wcg200 wireless function and just going from there... Any suggestions on a new/reliable wireless router? If thats my only course of action left. Oh yeah, I have reset the WCG200...and reset everything the factory defaults...and as other posts have stated...I too discovered NO FIRMWARE upgrade....nice job linksys!
