Asus ac86u router slower than new virgin hub

I’ve just moved and upgraded from 350mb to 500mb however was only getting 250mb speeds. I reported this to VM and have got a new virgin hub 5 from a VM engineer installed today. 

The hub is currently in router mode (my old hub was always in modem mode) and the devices connecting to that get the full 500mb. My asus router still works (not sure how) and all devices connected to it still work. 

Logging into the router and running the in built speed test it says it is getting 500mb however, the devices connected to this only get around 200mb. Hard wired via Ethernet seems to be getting 500mb so I’m sure the router is the issue. 

The old hub/router used to give 350mb before moving. 

Firmware on the asus is all up to date.

 

If I connect to the VM new network, I get the expected 500mb but I would rather use the router as better range on the WiFi and it;s all set up for the whole house. I also din’t want to have to reconnect everything over to the VM network particularly  

 

I appreciate that this is more a router issue than a VM issue but was hoping someone might be able to assist. 

Cheers,

 

Affy

    When you say “Logging into the router and running the in built speed test it says it is getting 500mb however, the devices connected to this only get around 200mb” are you referring to the ASUS router?  If so this sounds like an ASUS issue and not a Virgin Media issue.

    If you were previously running in modem mode and just plugged the ASUS router into the VM hub which you have stated is in router mode then you will get no end of problems. Among problems are double NAT and 2 DHCP servers. Put the VM hub into modem mode and then see what speeds you get.

      I did try this earlier. It didn’t make any difference. I’ll put it back in overnight and see in the morning if it helps. 

      I only put it back so I could access the VM 500mb

    It is odd how you get slow speed now...by wire I take it?

    save the Asus  config then reset and test again for testing speed you can keep hub in router mode for now and connect the WAN port of  Asus to hub then wire test speed to Asus.

    are you using Asus firmware?

      No wired seems fine. But the wired connection is also coming from the Asus which appears to be getting 500mb.

      I have reset ASU’s this morning but still the same. 

      So currently, vm hub in modem mode, hard wired to asus. In asus settings, speed test shows over 500mb:

      From the ASUs, the Apple TV, Denon, ps5 etc all hard wired. They get 500mb:

      I know about the wires - I’ve ordered some trunking…

      But WiFi connected devices are only getting 294mb

    I have the same router and it's excellent. However it's important to disable adaptive QoS.

    If that fails also try disabling beamforming in Wireless /Advanced.

      You sir, are a gentleman and scholar. This seems to have worked. Thank you so much.

      It’s started dropping speed again - it was doing ok for a few days but last couple of days has dropped back to 245mb on WiFi. Wired still ok. 

      Any other suggestions?

       

      cheers,

        I hate myself for doing this but I put it through AI and this is what it spat out.

    The Asus RT-AC86U with WiFi 5 (802.11ac) is at a disadvantage against 
    the later spec VM Hub 5 with WiFi 6 (802.11x).

    For recent mobiles & laptops etc with 5GHz WiFi 6 (802.11x), 
    working with the matching Wi-Fi 6 of the Hub 5 is likely to be faster.

      Thanks. This does make sense. The ai answer above seems to be working at the moment. If it doesn’t I think I’ll just give up and revert to using the VM hub.

        Hi Affy9 👋 Welcome back to the community forum - thanks for posting!

        It sounds like with the help of other community members you've been able to identify the issue with your 3rd party equipment. Sadly we are quite limited with the support we can provide for these kinds of queries, where you are using your VM hub in Modem mode, as we can't run testing in the usual ways. We also can't offer support with any troubleshooting for 3rd party equipment. 

        If you continue to see speed issues whilst running the hub in router mode please return to the thread and let us know! We can then offer further help. 

        Wishing you all the best! 🌞

    No reason why the Asus router can not be on the end of a long network cable and in AP mode to give you additional Wi-Fi coverage and network sockets in a different part of the home.
