R7000 - ISP Says My Router broadcast is Interfering w/ ISP's Incoming Wirless Signal

Deb- i work for a WISP and can help u out.

Are u in the US? If so heres some info for u.

Most WISPs use the same frequencies(2.4ghz and 5ghz) that wifi uses. This is because theyre free unlicensed freq. available for everyone to use. if a WISP used licensed freq, then the service would cost a whole lot more due to the FCC liscense costs.

When they say they can "see" your wifi signal, this means that your CPE(customer premise equipment) radio on the roof( which is acting as a station to the WISPs access point on their tower or building or wherever its located) is seeing the wireless signal that your router is broadcasting. A CPE is functioning similarly to what a phone or wireless computer does- it sees all the wifi signals that are available. This is normal.

The first thing u need to do is find out which freq band the WISP uses. If 2.4Ghz and all equipment u have operates on 5ghz(only talking about wireless devices here not wired), then u could turn off the 2.4ghz wifi on the Nighthawk.

However, if youre like most people, u will have a mix of devices where some have older 2.4ghz only radios.

In that case, the best thing u can do is make sure youre on a different channel than what the WISP is using. For 2.4ghz, theres only 3 non overlapping channels- 1,6,11. This means, if youre on chnl 1 and the wisp CPE is on 3, then there will be interference between the WISP CPE and your router.

If the WISP CPE instead uses 5Ghz freq then its a little more complicated due to MIMO and upper and lower channeling.

Once u separate the 2 devices as far as channels go, moving your router farther away from the CPE should help.

As far as IP address allocation goes, that has nothing to do with wireless signal interference between the 2 radios. IP address conflicts is a whole nother issue. If youre having that issue as well, it can easily be fixed. But lets get the wireless interference issue fixed first.

Hopefully this helps. If u have any questions, feel free to ask away!
