Here is a summary of the problem. This has been occurring on and off for almost a year and is annoying to the point where I have no idea what to do. I am fairly tech savvy but this one eludes me:
I have repeatedly setup 2.4ghz and 5ghz wifi on 3 different routers. In hours to days of time, almost all wifi internet stops working on all 3 routers BUT if you hardwire the device through the router it is working fine. I have this wireless internet issue with 3 different cell phones (LGV20 x 2, 1 Samsung Galaxy S4, 3 tablets (Amazon fire x 2 and 1 Samsung Galaxy Note 2014 edition), a Nintendo Switch, a laptop computer and an Nvidia Shield TV.
My Acer Aspire v Nitro can connect and get wifi internet access to the 2.4ghz but not the 5ghz. The other devices above cannot get wifi internet on either channel. I have an Nvidia Shield TV that is hard wired into the same connection through the router and no issues - streaming video works fine.
I have 100mbs cable internet from Time Warner (now Specturm). I have changed DNS to 8.8.8.8 and 8.8.4.4 to see if somehow it is a DNS issue (vs DNS from Specturm). This does not do anything.
I had a lower end router with these same issues that I replaced with a Netgear Nighthawk R7000 Mimo smartrouter. This had the same issues after a period of time (about 2 months) so I replaced it with a TP-Link AD7200 router. This router now also has the exact same problem. It had no issues for about 4 months but is now doing the same thing as the other 2 routers.
I have also changed channels and used signal strength meter (its always max signal, we have a small place). This issue happens when 2 feet from either router or in the other room etc.
I have factory reset the Nighthawk and the TP-Link a few times and reset the wireless connections.
They both work for hours to days and then once again start blocking all wireless internet access. Both devices will also start randomly blocking wifi logins to various devices - for example allowing login to 2.4ghz but repeatedly saying that 5ghz is wrong password or vice versa. On a different device I can then login to the "blocked" channel with the exact same user/pass and it connects to the network. Sometimes power on/off fixes this, othertimes the only solution is to factory reset the routers.
Because this issue is happening on 3 separate routers makes me think that 1) Cable internet provider is somehow "spiking" the internet connection to mess up the router (we do not subscribe to cable TV), 2) someone is actively trying to hack the router connections and the router blocks access, 3)
