I had a problem a while back where I would lose my internet connection whenever I got a phone call on my land line.
Turned out I had a cordless phone on 2.6ghz, and I was also using 2.6ghz WiFi. Upgraded the access point to 5 ghz, and the problem was solved.
Bear in mind WiFi can also suffer from bandwidth overcrowding, depending on the number of neighbors you have.
As others have suggested, I would plug the computer into the modem directly, bypassing both the questionable router and the questionable WiFi, and see if things improve. Next, I would plug the router into the modem and the computer hardwired into the router. If things are then OK, it would point to WiFi problems.
If WiFi's the problem, try to get the WiFi onto a different channel or try a different access point. In my case, I added an Apple AirPort, operating on 5ghz, in bridge mode below the D-Link router plugged into my Verizon FiOS box (and providing WiFi on 2.4ghz). Also, I eventually replaced the 2.6ghz cordless phone with a $20 5ghz model. Currently, both WiFi networks are OK (the 2.4ghz provided by the D-Link and the 5ghz from the AirPort).
