Well, this might sound crazy, but...… I am a frequent visitor to resale shops like Salvation Army, Goodwill, etc. This is because I am cheap and I like to support those organizations. Anyway, over time I have purchased routers from these establishments.
This means that at any time, I have at least 3 to 4 different routers But, for some reason, sometimes its signal it sends out wirelessly diminishes.
The other routers are connected to it by that fatter than normal phone line (I cannot remember its name). There is also a "Router Extender" connected to one of the routers. The "Extender" is in a separate location away from the other routers and is used to extend my connection to very remote locations on our property. (BTW, I bought the extender at a resale shop!)
So, when I have an internet problem like "weak signal" or another problem, I just click on my icon and search for one of the other routers that has a stronger signal.
Also, I put a timer on the routers that shuts them down electrically for about 30 minutes and then restores the power to them. I set the timer to do this at around 3AM. My partner says that this allows the routers to shut down and reboot themselves every night.
For some reason, one of these methods work and I no longer experience connection problems.
Also, if all else fails, I would also suggest going to your local library, Starbucks, DD or fast food business and connect wirelessly to their free WiFi.
