Virtual Desktop network spikes: Are there routers in the UK that support 5ghz channels over 48?

I am currently on BT 500 fibre broardband and using the BT Smart Hub 2 as our main router but trying to get it to work smoothly with virtual desktop using my quest 2 is a real pain and I can't get a smooth stutter free PCVR experience without massive lag spikes.

My PC is connected to the router using ethernet and the quest 2 is the only device connected to the 5ghz network but I will occasionally get network lag spikes over 100ms within 5 mins of playing - virtual desktop settings are default.

I have used a wifi analyzer and all the 5ghz channels (32-48) are congested with other 5ghz networks around the neighborhood. However, from channels 52 upwards, it is completely free and empty but the hub only allows me to select between 32-48.

Does anyone know for sure routers that offers channels over 48 as this will hopefully fix the issue with the lag spikes I think.


Thanks

Are you sure congestion is causing your issues? Is the router in the same room as where you use the Quest 2?

Yes, I am playing in the same room and I am around two meters from the router.

Every time I get frame rate drops I notice the network latency goes red and spikes to around 100ms on the OSD and CPU and CPU usage is nowhere near 100%.

If the problem isn't congestion then what do you think it is?

I don't know, how many 5ghz networks are around you? 10? 50? 100's? Are they strong signals? Are you getting any disconnects at all? How is your signal strength on the Quest 2?

Is the network cable between your PC and router a cat 5e or higher?

Have you tried using the Quest 2 very early in the morning or middle of the night when these other networks are quieter?

So just a quick update on this.

The BT smart hub has only one SSID whereby you can't split the 2.4ghz/5ghz bands. I also have a mesh system connected to the hub but that also has one SSID and no way of splitting the bands.

So even if I have disabled the 2.4ghz band on the hub and kept the 5ghz one just for the Quest 2, anyone in the family who connects to the mesh system is automatically connected to the faster 5ghz band by default and in the end, everyone ends up using the 5ghz and that is when the network latency spikes occurs.

I tried playing with Half-Life Alyx on the quest 2 for at least a couple of hours without anyone else using the wifi and it was pretty solid with no network lag spikes.

Why on earth doesn't the smart hub 2 allow you to split the 2.4ghz/5ghz bands and create separate SSIDS as that would have fixed the network lag spikes.

What are my options other than getting an access point or extender for getting 2.4ghz network just for the family?

Thanks
 
I have the Tenda Nova MW3 and it is connected to the hub via an ethernet cable, however every device that connects to it is automatically connected to the 5ghz band by default and there is no way of disabling the 5ghz band.
 
Hmm, I think may still have a Virgin Media hub 3 lying around in the garage that I could try and I do think you can split the bands with that router but will it work with a BT fibre line?
 
Quick update:

It turns out that I don't have the virgin hub after all and must have sent it back when I switched over to BT.

I also ended up disabling the BT wifi hotspots that are on by default on the smart hub and since then I have had quite a several long sessions of Half-Life Alyx and finally managed to complete it (wow what an experience!) with no network spikes.

Half-Life Alyx is very hungry and it has to be running with steamvr in the background which doesn't help with performance. I find that if I log out and login again, it resets my vram usage to around 500-600mb and when I play HLA for long sessions, it is a smooth experience with no performance hitches if I relog.

I now try to avoid using steamvr altogether and try to force either Openxr via VDXR or Oculus runtime in games as they perform much better than steamvr on the quest 2 and together with FFR, I get massive performance uplifts with no picture degradation on my vr games!

So I am now fairly happy with the performance of VD and hardly get any more network lag spikes.

Thank you for everyone's help and contribution :)
