Router is a X6 R8000 Modem is SB8200, my own and new I have Gigabit Internet Router is nowhere near enough to other 2.4 or 5 Ghz devices to cause interference. There is one wall between me and the router and the router is no more than 30 feet from me. I had multiple drives on my network, disconnected all of them. Three Roku's, two are off. One is in use. One Chromecast Have a couple of IHome Mini's but this was going on prior to purchasing them. Couple of cell phones but it doesnt matter whether they are attached or not. I paid the $400 pro installation for 1 Gig. The Modem never flashes or shows that there is no signal. The router never shows there is no signal. But there is no signal intermittently, enough that it is definitely getting irritatiing. At first I thought it was their (Provider) equipment. Changed Modem. Didn't work. Replaced my Nighthawk X4S to the X6. Didn't work. I added an X45 2700 extender 30 feet from the router. Didn't work. I have made changes to every setting. Nothing works. Removed VPN and shut off DNS server. Changed nothing. Removed everything except one laptop to test. Still did it. Checked neighbors channels and moved my 2.4 and 5 to fixed channels out of their range. Changed nothing. Reset modem and set everything back up. It fixed nothing. I have done quite a few hard resets, that does nothing since there appears to be nothing wrong to the outlet (Modem) anyway. There are no Guest networks on. It is both frequencies this happens on. Weather is not the issue, it does it in all weather. Signal strength from neighbors is not the issue. One neighbor is running an X46 with strong signal strength but when I check it is always on different channels. Other neighbors are too far away to interfere. There should be absolutely nothing wrong, but my connection goes in an out constantly. You get maybe 15-20 minutes before it goes out. Comes right back on. Repeat. Suggestions on what could be causing this and what to do about it would be greatly appreciated. With an SB8200 nd a Nighthawk X6 plus an extender 30 feet from the area where there are two laptops, two phones and one TV with Chromecast and a Ruku Stick, this should not be doing this. HELP!? Also all Firmware is updated and laptop drivers are up to date.
