ORBI5000 network

A neighbor recently installed a new router and it is wreaking havoc with my network. I run an Asus Dark Knight and have never had issues but now I've had interference. Using WiFi Analyzer I see a network named ORBI5000 and it's running on 2 channels (eg 7&11) at the same time. Sometimes it bounces down to 1&5 too. So there is no way I can get away from it without overlap. What's the deal with this thing? Why the dual channel 2.4 signals? Any info greatly appreciated.

Re: ORBI5000 network

Orbi will use 40 MHz bandwith (2 channels) on 2.4 GHz, unless the owner has the "Enable 20/40 MHz coexistence" option enabled.  Plus, the current Orbi firmware allows no control over the output power. If you set your router to 20 MHz, channel 1 or channel 11, you maximize your chances for coexistence. Or you can go talk to your neighbor...

Re: ORBI5000 network

Thanks! I will go talk..but wanted to make sure I wasn't wrong before I brought it up. Is there any advantage/disadvantage for the neighbor's network to having it set up the way they obviously do?

Re: ORBI5000 network

The advantage of using 40 MHz channels is the transfer speed on 2.4 GHz is increased by about 2X. The downside is almost no ability to avoid interference from/with neighboring APs. The interference will reduce your throughput, so the benefit could be theoretical only, unless your house is a cabin in the woods. If throughput is critical, then 5 GHz devices should be used anyway.

 

The recommendation from the pros is to only use 20 MHz on 2.4 GHz and to manually set the channel to 1, 6, or 11. Don't use Auto channel settings.  You could agree with your neighbor to use channel 1 while he uses 6, or something similar. You both would benefit.

Re: ORBI5000 network

Some more information that might help you:

 

Orbi will always try to operate with a 40 MHz wide channel in the 2.4 GHz band. If the coexistence setting is ticked, then Orbi will fallback to 20 MHz if interference from a neighboring AP is detected.  So, your neighbor cannot explicitly set a 20 MHz channel width.

 

The only way to operate inteference free with 40 MHz is with one router on channel 1 and the other on channel 11, and one of the routers using 20 Mhz width. 

 

 

If your neighbor sets channel 1 and you set channel 6, he would fall back to 20 MHz width.  But, if the neighbor sets channel 1 and you set channel 11 (or vice versa), then he could continue to operate at 40 MHz and neither of you would interfere with each other.

Re: ORBI5000 network

Thanks! 

 

So what i surmise is that, while the neighbor's network is interfering with me, perhaps mine is not interfering with theirs. So.... if I buy an Orbi and blast it back at them perhaps we'd both default to 20 MHz..haha

You could do that. Smiley Happy

 

The important thing to note is if the coexistence setting isn't set, then the Orbi just blasts away on 40 Mhz, regardless of interference.
