GT-BE19000AI Wifi 7 Issue

[ApexAvian]

I have been encountering a perplexing issue with wifi 7 devices connected to my GT-BE19000AI. I have the latest firmware installed, AFC enabled, and QOS disabled, but starting yesterday after my google fiber install I began experiencing severely reduced speed and lag with my wifi 7 devices. I'm lucky to get 300Mbps with a 3 gig Google Fiber connection standing next to the router with a 320 MHz Intel BE200 card device. If i force the 6ghz channel bandwidth to 160 MHz, my speeds improve to nearly the max allowed for that bandwidth.

For example the day before I was getting download speed of 905.99 Mbps, the max my old 1 gig AT&T fiber would allow, after the google install and router firmware update I'm only pulling 447.04 Mbps. Wired speeds are fantastic. At 160 MHz, I'm pulling 1,506.94 Mbps.

Any ideas on what could be going on?

I performed a factory reset and rolled back the driver to the previous release, but the problem persisted.

Check System Log, Wireless Log for clues. It shows RSSI values and link rates.

Which firmware version specifically?

What is your AFC allowed bandwidth?

MLO enabled or disabled?

MLO is enabled but i have not set up a MLO network.
Firmware: 3.0.0.6.102_40383-g12871f8_1514-g9376d_BB0B
I don't see allowed bandwidth but its on standard power.

I have been looking through the logs but nothing jumps out. It all indicates good link rates and RSSI.

The AFC allowed is in the app. (Not sure why I can't find it on the Web GUI but maybe because you need the app to activate it).

-> Settings -> WiFi -> AFC -> 6 GHz Channel Bandwidth

Should look similar:

Okay. I have been forcing the 160mhz through that menu. I uploaded screenshots to the previous reply.

I saw them. There's something causing noise/interference on the channel so ping is so high 1xxx. (Strangely it is usually upload or download, unless you do something seriously wrong like I did recently and put a 2 Amp vs 3 Amp power supply)...

Strange that the upload seems fine.

Is there a UPS nearby? I recently installed a USB 3.0 HDD but seems it is not causing issues. These are the main sources of noise I have had to deal with. Also even with 2 GB memory it could cause high memory utilization (4 TB HDD) on my prior main GT-BE98 Pro as SMB caches up 95+% of the memory...

Try creating an MLO SSID and connect to it... I believe the Intel BE200 can handle higher throughput.

Yes there is. The router and gateway are connected to a UPS. I'll remove it later and see what happens. I'm also going to try the google fiber provided router to see if it improves.

 

[jzchen]

Sorry I said it as fact, I suspect there is noise/interference....

 

[jzchen]

They have different versions, but if you find things return to normal and still want to use the UPS, I have one of these installed which helps:

Didn't the listing above indicate "acceptable" noise floor ?

It can go through the power line. I have a (some Chinese LiFePO4) sine wave UPS, it is maybe 10+ ft away from my BQ16 Pro. I still had strange speed test unless I don't use it or that Isobar with EMF/RFI filter...

If you pardon/ignore the mess I can take a picture...

 

[degrub]

You could always put a clamp on RF choke on the device end ( or pull a couple out of an old vga cable ;-) ). We used to use those on VGA cables to CRT and LCD panels to dampen any picked up noise. Won't work as well on normal mode noise or jitter in the output of the power supply. They have to catch it in the output stage of the power supply.

If enabled, DISABLE all of the AiProtection tabs/settings and reboot router.

 

[bennor]

If enabled, DISABLE all of the AiProtection tabs/settings and reboot router.

If disabling AiProtection features make sure to Withdraw from them as well on the Administration > Policy or Privacy page (or where ever the option is in the GUI).

 

[jzchen]

My bet's still on UPS noise until OP tries to remove it and it doesn't help doing so....

Latest firmware _40383 says it resolves the AiProtection speed penalty...
