I apologise if this question has already been addressed - I have looked but not seen anything similar.
Setup: Orange ISP with ADSL connection Dell PC (Windows 7) with wired connection to D-Link DSL-G624T router Laptop (Windows Vista) wirelessly connected Laptop (Windows XP) wirelessly connected
Over the past couple of months the PC has been getting more difficult to connect to the router. Sometimes just a Restart would resolve the problems, other times the PC and router had to be powered off and on. Nowadays it may take multiple restarts to get the PC to recognise the router connection.
The router powers up but the PC is not linking to the internet. The two laptops though can still connect wirelessly. So, presumably, the router is OK.
I have changed the cable between the router and PC without it making any difference.
Is the problem possibly with the card in the PC? I haven't changed that yet. If it is not the card, what else could it be?
The network card is likely to be built in to the motherboard , uninstall it from Device manager and reboot , also try downloading the latest drivers for it , although I would imagine as a Windows 7 PC it probably has the latest ones already
