Asus Router Not Reaching Full Wireless Speeds on Superloop 250/25

Hey OzBargain!

I recently upgraded the home internet to superloops 250/25 plan. Through a wired connection I'm getting speeds anywhere between 250-270mb down and about 25up… so far so good!

Unfortunately, my router isn't providing full speeds through 5ghz. My current setup is an Asus RT-AX55 and an Asus Rt-AX53U as a mesh node. I'm getting about 25upload but only 150mb download. I do have approximately 15 devices connected at any given time (with a few of those being wired) so that could possibly reduce the speeds?

My routers CPU's aren't even close to being stressed and I've also turned off the QoS features on the router with no differences so far. What else can I do to possibly increase by wireless speeds?

Thanks!!!!

    What device are you connecting to, is it wifi 6? And how far away is it/what walls are in the way?

      Currently my device of priority would be my PC which is between 1 wall from the mesh node, between the mesh node and the main router its between 2 walls but a good 15-20ish metres. In terms of range I get full bars even when I use only the main router. The PC connection is also using wifi 6.

    That's just the limitation of wifi when you use it as the backhaul for mesh network. If you login to your ASUS router then click AI Mesh, then click on the on the secondary router you should be able to see what the PHY rate is. In my example, my AI mesh routers are using 5ghz as backhaul. My desktop is connected via ethernet to the satellite node (AX-55)

    You will see that it's usually significantly slower than wired gigabit ethernet

    WiFi is half duplex, that already cuts your bandwidth by half, then after taking into considerations like interference the real world performance is much worse than what you see in your ASUS router dashboard.

      Thanks for the comment. I just had a look and the 5ghz line on the RT-AX53U tab the PHY is 390mbps and receive is 585. It's a real shame as these routers (and I'm sure not just an asus thing) are rated for considerably higher rates. Also a shame that I physically can't have my PC directly through ethernet.

        Connecting the two routers together with ethernet cable would solve the issue, but if not possible consider moving the router around so that your node can better pickup signals from your main router.

          That would be nice to do, double story house makes that difficult. Everything is in it's best possible spot, might just have to suck it up. Better now having 160 down than 100!!

    I get 250 Mbs download to my pc when performing an ookla speed test on my TPLINK AX55 to RE605X setup, which is very similar to yours as in they are both AX1800 and are mesh like the Asus RT devices you have.

    Are you using ookla speed test to test the speed?
    Are you testing at different times of the day & night? It can vary allot.

    • banterbants on 29/04/2024 - 21:01

      Yes I've been using ookla for PC speed tests, Done both day and at night. I'm unsure on whether its worth removing the mesh and just trying one router and seeing how that goes?

      • AndyC1 on 29/04/2024 - 21:18

        Worth a try as it's not due to congestion at night.

    I had same problem with my new rt82u. Called my ISP a number of times to rule that out. They eventually got me in to Asus support who ran through a range of options including manually updating the router software. They eventually said the router is probably a dud and I should return it? Based on their advice I got the feeling it’s not an uncommon issue. My very old dlink ac router was much faster and provided better coverage.
    I did buy the asus thinking it would give me a little bit extra but have been disappointed.

    • banterbants on 29/04/2024 - 21:08

      I got these routers when I had lots of issues with my previous IP… fixed every single problem. Now I've got this small issue of not getting full speeds on 5ghz when I thought I would based off the specs of the products.

    • Check the wireless protocols running on both devices - e.g., make sure you're not set to 802.11n.
    • Check how the mesh backhaul is configured - if wireless, it'll be introducing a lot more wireless congestion.
    • Download WiFiman and check to see which wireless channels your devices (as well as your neighbours) are using and adjust as necessary.
