Wireless Internet Access Problems

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.

I ran a helpful free program called WifiInfoView and it seems the majority of networks in my neighborhood use 1, 6, or 11 (as expected). However, there is only one network that uses channel 9, and it appears to be far away from us, so I'm thinking this might be the best channel to switch to. Any thoughts?

It would certainly rule out interference as the issue, as in if you still get the same problem on the new wifi channel its obviously not a channel issue.

The only other thought I had was whether there is any commonality in your laptops wifi adaptors? make/drivers/firmware revisions etc.

I've googled windows 7 limited wifi access and there's a lot of info out there on being able to connect to your local network but not the internet, so it may be some quirk of windows 7 but what exactly I couldn't say.

Try the channel change first and maybe peruse some of the info on the windows 7 issue in the meantime. Beyond that I'd struggle to think of anything further.

Hope you get it nailed.

Actually the wireless repeater I bought is still too new to determine if it has done anything. It could be interference between the basement and the upper 2 floors for all I know.

Ok so we did end up switching to Wi-Fi Channel 9 and so far things seem to be working very well. We only had one "outage" so far and upon doing some research it seems that our ISP was reporting internet service degradation in our area, so it wasn't our fault. I had a feeling the problem wasn't that complex.
