I had that issue over many networks and wrote about it at this link -> http://forums.cnet.com/5208-6132_102-0.html?forumID=32&threadID=242736&messageID=2457489
Besides that, is your router firmware the latest?
mesh desktop pc with windows xp sp2
belkin pre-n router
d-link usb adaptor
when connected without security (password) i have intermittent connection, and (as is the case right now) sometimes, my internet connection icon tells me i'm not connected although i am.
when connected with security and password, my internet connection icon tells me i am connected with 54kbh and a strong signal, but i cannot even connect to my homepage in this state, and occasionally on connection i am met with the error message:
the network did not assign a network address to the computer
i have tried resetting the winsock thing as described in another thread, but to no avail.
any help would be greatly appreciated.
thanks in advance.
