Bewildering Limited Connectivity

I live in a village in the Republic of Georgia with a Georgian family which has been gracious enough to facilitate wifi, set up by an ex-son-in-law, a mailman who is still the family tech go-to (and speaks no English, like the rest of the family). Our current internet provider has worked well for the past month. As forewarning, my computer knowledge is not great.

A few days ago I traveled from Georgia to Armenia and back. When I returned, I could not use my home network--I was getting "limited connectivity" (as in, the little yellow triangle). I have not since had this problem on my school network, but my wife's laptop, since our return, has also intermittently been unable to access the internet--often (though not necessarily) when I can, and vice-versa. Hers seems to be able to access internet far more often than mine.

The Windows diagnostics tool has been unhelpful, and usually claims it can't figure out the problem. I have tried resetting the adapter and the router. I have updated my drivers. I have renewed my IP. I have restarted my computer. I have run a malware scan.

Three times I got internet back, but each method (the first two, anyway) has only worked the one time. The first time I fixed it, I disabled all wifi "items" except IPv6/IPv4. Internet was immediately restored. It remained operational after I had re-enabled these items, all afternoon, until I slept and re-woke my computer. The second time, I turned off my antivirus shields. Once again, when I re-enabled them, internet remained. Similarly, having slept my laptop and re-woken it, I lost internet again, and now fiddling with the antivirus doesn't have any effect. A third time, just now, I turned off IPv6, refreshed the connection, and turned it back on. All of a sudden, internet. We'll see how long this lasts.

I do have the username and password to the router and can adjust the settings from my laptop. I have not yet tried to communicate the problem to the son-in-law; due to the language barrier, and as I'm not sure whether his technical abilities will be able to determine whether it's a problem with my computer or the router, I'm saving that as a last resort.

Any help would be appreciated.

Here is the latest ipconfig readout from command prompt, while the internet was down:

As an update, I'm still experiencing difficulties, as is my wife (and once again, often when one laptop isn't working the other is). The only solution that seems to last beyond a computer sleep is to lock the IP at 192.168.1.154. That will last for a day or two before I have to start over.

TerryNet, the first ping was successful and the other two were not.

 

Yes, I believe so.

 

Maybe they are somehow getting the same IP address via DHCP. Or something is getting a duplicate IP anyway. Odd, but I've seen it happen. You could try putting static IPs on both devices and see if that eliminates your issue.
