I have my main pc in an upstairs bedroom and router downstairs I have been using an older model belkin adapter which worked fine for a couple of years until around two months ago when It started disconnecting intermittently to solve this I normally pulled it out of the USB port and plugged it back in. However it kept doing it more and more so i thought the adapter was bust so bought a new belkin N300 however this is worse and I cannot connect at all now. The signal strength is excellent and all my other devices(laptops,phones,ipods) connect to the internet and the router with no problems but my main PC doesn't. I have had network sharing center on and it connects to the internet then disconnects from the modem then re-connects then dis-connects its so frustrating I have no idea what to do. I have read some posts and checked certain things but have no idea how to progress.
Many thanks
