Best Router for Local Multiplayer VR?

Wi-Fi 6 I can personally vouch for the ASUS AX1800 or AX3000 routers. Avoid TP-Link and Huawei Wi-Fi '6' routers for VR gaming specifically, they're know to cause issues. Their Wi-Fi '6e' routers are fine though. In terms of connecting multiple headsets to the same router, do you mean you're playing

High net latency on Galaxy Tab S9?

For context my router supports WiFi 6, a TP-Link AX1800/Archer AX21. I'm on the 5Ghz AP with no other devices connected or APs in range, in front of the router, and I get 40 to 90ms on this tab. Somehow on my Legion Go (it's like a Steam Deck) I get around 1ms network / 1ms decode even behind walls.

Support for TP Link Archer AX1800

This is a few years late, but... for anyone who thought it would surely be finished now: TP-Link AX1800 AX21 router uses the Broadcom BCM6755 system-on-a-chip(SoC). Broadcom is problematic in the best of times, but this SoC is especially "un-open". So it won't ever be supported in the foreseeable fu

Internet Speed Slower

The Asus ROG Strix B550-F motherboard (with its Intel I225-V 2.5Gb Ethernet) and the TP-Link Archer AX1800 router are physically compatible, but they frequently experience auto-negotiation link drops and disconnection issues due to known bugs in early revisions of the Intel I225-V controller.

Outdoor Helium Wi‑Fi Hotspot suddenly won’t let my phone connect after router change — anyone else seen this?

An AI suggestion....The potential problem: The new TP‑Link AX1800 likely has default firewall settings, an SPI Firewall, or TP-Link's HomeShield active. These features frequently drop IPsec, VPN passthrough, or the specific tunneling ports the hotspot needs for client authentication. The phone sees

Frontier ONT

Hi,

I'm wanting to use my own router (TP-Link AX1800 Archer AX21) instead of Frontier's provided router but for some reason when I connect to their ONT (Nokia G-240G-A) through the active port, I get no service. Even if I connect directly to my computer, again no service. It only works when conne

Can't get smart plugs to connect no matter what I do

I have had the same 4 smart plugs for some time now, and I've never had this much trouble getting them to work. Just moved, and now I have spectrum internet, so I went and ordered a new router (tp link archer ax21) and set it all up. Made a guest network for smart devices that's 2.4ghz only, just li

TP-Link mesh help axe95 and ax21 how to

With your help I think I discovered the issue. Of course it has to do with TP-links confusing naming scheme. The ax21 already has a firmware update that enabled "Easymesh". The AXE95 is marked as "planned" to support Easymesh on the TP-Link website. So the AXE95 can only do OneMesh, which, also on t

TP-Link mesh help axe95 and ax21 how to

Based on the way TP-Link advertises this, I figure this would be an easy addition when I originally purchased my Archer AX21 2 years ago.

Downstairs office has always been a little slow as is the kitchen bar. Now I would like to improve using their easymesh or onemesh (It looks like AX21 support

Clients can't connect to wifi and I have to reboot

Hello,

Firmware Version:

Hardware Version:

Most of the time it works fine. Periodically, some of the clients can connect to the wifi and I have to reboot it. Well, maybe I don't _have_ to reboot i
