Most of the time when I start-up my PC my WiFi card does not pick up any networks, however if I reinstall drivers the issue gets fixed. The adapter also works without the drivers on the CD that is given with the card, but also has the issue of not working on start-up. I had initial issues with a USB adapter that was giving very high latency between my pc and router, so I bought a TP link WN881ND V2 card. I still had high latency, so I had the adapter replaced with the same type of card ( WN88ND V2 ). Now I have the issue of occasional high latency and frequently have the issue mentioned at the beginning of the thread. Any ideas on what could be the problem?
