R7000 - ISP Says My Router broadcast is Interfering w/ ISP's Incoming Wirless Signal
I have wireless ISP service. There is a 'radio' receiver on the roof which receives the signal from a repeater in the neighborhood - it is line of sight transmission. From there it is wired into t...
- 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!
I always find it strange that Wireless ISP (WISP) would pick a frequency range to transmit your WAN services as the same used for a Wi-Fi LAN. How do they know it's you and not one of your neighbors that interfering with your signal?
If you're on Channel 1 and they're on 8 have you verifired that this isn't a channel width and overlap issue? It's possible your WISP's equipment has also a very wide channel width it receives. Just for troubleshooting purposes, have you tried with the Channel 1 to set your Channel mode to the lowest "up to" setting to the lowest value ("Up to 54 Mbps" )? Also, make sure you have enabled 20/40 MHz Coexistence (Advanced Setup > Wireless Settings > Enable 20/40 MHz Coexistence).
Bryan!
Thank you also as your answer was right on and I also got the other similar answer just before I called my WISP. Axeing the 2.4ghz broadcast solved (most of the) problem - see othger post! And I did select the lowest lowest value ("Up to 54 Mbps" ) although my chioces for the 5ghz broadcast were much higher : 289, 600 & 1300. My WISP said that would help!
I never found a 20/40 MHz Coexistence setting. I'm wondering if that applies to 5ghz? or only 2.4ghz?
Also when I was on the roof, I saw that the WISP signal was VERY WIDE - covered from 1 to about 6 or 7 but was hugly weak -90 to -100 & sometimes non-existant. Funny, other techs of thiers told me it broadcase on Channel 4 but this tech would not tell me the channel - go figure. But, now that I'm on the 5ghz broadcast for my router, apparently the channel does not matter?! NO mention of selecting a better channel on 5ghz. Also very odd - there are 2 towers broaddacting on our rural neighborhood and I was seeing the signal of the one I am not connected to and could not even see the one he said was stronger for our location and that I am connected to - go figure on that too!
Problem solved for now once we get the wiring issue fixed. Thanks again for your help! Deb
