BGW320-505 using 160 mhz has issues

I have 1 Gb fiber internet through BGW320-505  (and receiving on wifi 6 pci card  one room over) and have been trying to be able to utilize the full Gb speeds over Wifi but am having issues that I believe stem from the BGW320-505. I'll state what's happening below:

> When transmitting the 5 ghz signal with 80 mhz bandwidth, I'm usually speedtesting 500-600 mbps (which was close to what I was getting when paying for only 500Mb internet)

> When changing bandwidth to 160 mhz, I have been able to reach the full potential: https://i.ibb.co/cgfp5fC/Speed.jpg

> HOWEVER, the 160 mhz setting is inconsistent and causes many problems, with the speed fluctuating greatly and constantly. Here's a screenshot of the exact same setup but taken 1 minute later: https://i.ibb.co/r4S26wn/speed-slow.jpg

> What is causing this? I need a fix to utilize the full speed I'm paying for. Hoping for help!

> One thing I notice is the channel that gets auto-selected. When the channel is 161, the slow speed and constant changes occur. However, as seen in the first screen shot, when the channel is 112, I get full speed. However as far as I can tell ATT will not let you select your own channel, so I can't test this theory. But it's possible the 161 channel is bad, but the router keeps choosing it.

Thanks for any help!

Hi guys. I've been searching high and low on how to get a full 1 Gbps wifi speed out of my ATT fiber BGW320-505 and found this thread useful.

I have one more issue I'm running into. With the default 5gz, default channel, and defualt 80mhz bandwidth, I'm getting around 600Mbps on my desktop wifi 6 pci card. However as I'm paying for a full Gb, I'm wanting to try and find out how to get that in wifi speeds.

One trick I read was to change the bandwidth (BW) up to 160 mhz in the advanced settings, so I tried that. At first it was great! I was able to hit over 800Mbps. However soon after I started having a lot of issues with the speed, with it dropping down to 10 or 15 mbps, which was confirmed by looking at the Link Speed (eg. like 15/200). It was really all over the place.

When I turned the BW back to 80 mhz, everything was calm and consistent again with getting up to 600 Mbps. 

Anyone else have issues when using 160 mhz BW with this router? I want to be able to get max speed but the routers connection seems to get wild.

Hmmm I'm a little disappointed there have been any comments or support here at all over several weeks. No one knows anything about any if the topics I brought up? 🤔

There are quite a few different problems it could be.  With a problem like this I'd start with doing more precise testing.  Fast.com is good for quick tests to verify speed (and to verify an ISP isn't throttling netflix/video speeds independently of other speed tests).  speedtest.net is best for precise testing.  it's tests runs for a longer period of time transmitting and receiving a large amount of data.  
My understanding of higher bandwidth 80 or 160mhz 5ghz connections is that they combine multiple channels for instance on my netgear r7000p it might show it as 4 or more different channels together like channel: 116(p)+120+124+128 (I've always assumed the p stands for primary, but its just a guess).  The windows cmd might not be intelligent enough to show multiple channels being used. 
So the next question is are any of your neighbors using any of the channels you are using? They may be causing interference

160MHz width in the 5GHz band has a number of issues.

First there is only one 160MHz channel and you'll interfere with lots of other 5GHz bands.

Then half of 160MHz is in the DFS range which means that power level are different, there is potential issues with weather radars that force your AP to go to another channel (a particular issue near airports).

Finally, many older Wifi5 devices don't support 160MHz or don't do it well.
