WiFi Slow down intermittently

Installing and Using OpenWrt
1

Evening All,

Recently installed OpenWRT on an Asus RT-AC88U.
I'm running this as the main router via a Virgin superhub. I've noticed though that the WiFi seems to intermittently run really slow, dropping to some 3 to 5 megabits per second. If at that time I jump on to the superhubs wifi though it runs as it should at between 80 to 150 megabits per second. So it doesnt seem to be the feed to the house causing issue, instead its something betwee. Virgin hub to router, or wifi.

I was wondering if there any anything going on that might vlbe causing it?

Broadcom wifi isbreally tricky, you have to guess your parameters around to have it working at all, always check system logs for bcm and hostap messages when it happens. Also make sure you are not on 23.05.4

Thanks brada4.
Im sure my Archer VR2800 was broadcom as well and thar seems more stable, might have to go back to it if I cant get the RT-AC88U ro settle.
I'll take a look at the log files when it next does it, although Im no expert on what its going to be saying in the logs!

25.05.5 is what I would have installed, managed to do it first times via the Easy Installation method (CFE recovery Mode)

The newer the broadcom chip the less iit is / can be supported. Like zero support for brcm wifi6.

Anyone have any recommendeds as starting parameters / settings to get this router to have stable wifi performance with openwrt.
I believe its a BCM4366 chip

Probably get back to stock then to merlin if you want any customisations. Open drivers are not on par with bcm blobs.

Thanks Brada,
I moved over to Openwrt as I found the asus stock firmware was also quite unreliable.

Is Merlin decent?

It adds knobs on top of asus fw, which is relatively well maintained, like most N devices upgraded with wpa3. Other manufacturers just stop releasing fw once past warranty.
