I have several computers in my house, 2 Windows 7 laptops that are fairly identical (which use wireless connections) and a Windows 10 desktop in the basement (which houses a cable modem and a wireless router, it does not connect wirelessly, it uses ethernet). There is also another laptop the basement that connects via ethernet. We also have an X-Box 360 in the basement that connects wirelessly. There are several wireless phones throughout my house, a landline and several cell phones. We receive Internet and cable service through our local cable provider. Now let me describe my problem...
On occasion (usually every several days) the 2 windows 7 laptops will lose connection to the Internet, but not the wireless network (I know this much because I can still use our wireless printer successfully). I can also see other networks nearby, so it is not the fault of the wireless router or the laptop's network adapters/signal. The weird thing is that computers connected via ethernet will work perfectly, and the X-Box still connects to the Internet. This led me to believe it could be a problem with our ISP or cable modem, but if that were true, then the wired computers would not be able to connect as well, so I am fairly stuck on what the issue actually is since only the laptops have this problem. The only remedy is to unplug the modem, wait a few minutes and then plug it back in (and this is a newer modem too mind you, although we've had it for the past 2-3 years, we can't believe it would have died already).
In addition to turning the modem on and off we have tried changing our DNS servers (with little effect) and purchasing a signal repeater. Safe Mode with Networking also did nothing, so it rules out program interference.
If anybody is interested in helping me pinpoint the problem I will provide more specific information on the devices, but this is what's happening in general.
UPDATE: We think it could be wireless interference from neighboring routers also using Channel 6.
