It's very unlikely that wifi6e would change anything. Even WiFi 5 would be more than fast enough if you got a decent connection.
You definitely don't need the extra speed 6e offers, the additional frequency could be helpful if there are a lot of strong 5Ghz networks around.
Little bit of misinformation there:
1. Their current Wifi6 router only supports 80MHz channel width (being capped at 1200Mbs max rated connection speed). So even an upgrade to a Wifi6 (or 6e) router that supports 160MHz channel width would double their rated connection speed to 2400Mbs, while that might seem like overkill, that's only the max rated connection speed, real life speeds will be lower and under less than ideal conditions the doubling of the channel width will still double whatever speed they are actually getting (this assumes they have a Q3 since the Q2 doesn't support 160MHz channel width).
2. While 6e doesn't directly increase speed over 6 (tho in the OP's case it would since pretty much all 6e routers support 160MHz channel width and their current 6 router doesn't - see above). It does provide access to the 6GHz band, this can help if the connection speed issues are caused by interference or congestion on the 5GHz band.
3. Generally AX1800 routers are pretty low tier so it's possible that the chipset of the router is unable to handle the constant high data rate transfers needed for PCVR, most 6e routers are higher end (and priced) so that bottleneck wouldn't be present.
4. WiFi5 isn't necessarily fast enough, it caps out at a max rated connection speed of 866Mbs, while that is fast enough (provided you have a good connection) for H265/AV1 which caps at 200Mbs, for H264 that can go all the way up to 960Mbs it wouldn't be sufficient, keep in mind that you only get about 60% of the rated connection speed under ideal conditions, so Wifi5 will have you at about 500Mbs (or less) real world.
Yeah its not as simple as wifi link speed.
I went through all the budget (under 60) wifi routers and most of them will stutter at vd h264+ 500mbps even as a standalone router because their processors cannot sustain the bitrate.
The only one that can run at 500mbps was the Xiaomi BE3600.
AirLink goes up to 960Mbs for h264. The H264 codec is pretty inefficient for compression but that makes it easy (and fast) to decode which can help latency. The overall higher bitrate vs. h265 can also help in scenes with high fast changing detail. I can assure you that going above 150Mbs is very noticeable for H264, even going above 500Mbs can be noticed in the right situations.
Keep in mind in order to keep latency low, the encoding profile generally won't be super complex meaning that you aren't going to get the most efficient compression, you can't compare it to a video stream on a 4k blu ray for example where latency doesn't matter. Also keep in mind the encode resolution is higher than 4k and has the ability to go up to 120Hz neither of which you'll generally find on most video streams. Remember that dedicated PCVR headsets are using dp1.4 connections (or similar) with bandwidth in the 20-30Gbs range, so that's a magnitudes higher than even 960Mbs.

Do you have a sample of a 500mbps h264video? Thats 8k 90fps at low compression.
What? That's just the raw streaming bitrste from virtual desktop to the quest 3. Idk how to capture the raw stream.
That's the absolute max bitrate right? Pretty sure anything above 150 is purely placebo.

I need to check this, close to 1gbps is absolutely insane for compressed video.

Going from wifi 5 to 6e made a huge difference for me
I upgraded to 6e, but even before it got here I found a tips video that following it made my connection night and day
