When I first got Verizon FIOS, it was working fine, fast speeds (on both 5ghz and 2.4ghz), and for some reason as of late, I literally cannot connect to the 5ghz wifi, it has been in the same place that is has been forever, it doesn't work on any devices (phones, PCs, consoles, etc). I tried renting the extender, but there's no light on the coaxial signal and it just doesn't work.
Once again, it has been in the same place since i got it and now its acting up, I tried rebooting, resetting the router system, etc. And it's not like the signal is low or anything, I can connect to it, but when I do, i can't go on any sites.
Sometimes, I am able to connect to it and it works, but after 5 minutes, it starts to buffer, lag, then shutdown.
Please help.
