Connection is wifi 5G and seems stable until large data is being transferred where I have drops from 30Mbps to under 1Mbps and I need to reboot the router. Samba is not on and no other vpn clients are active when drops occur.
While that’s a nuisance, my biggest problem is the router working as a WireGuard VPN server. My wan connection is 500Mbps fibre and when I use it for travel I can barely get 20Mbps and often closer to 12Mbps on a 70Mbps line so I end up using NortVPN service as it’s at least three times faster. I think I have the wg server set up correctly as there wasn’t much to it. Only identifiable settings are that MTU is at 1400 as I’ve got the best speed and the the IP- masquerading is turned on. And my client router is the MT3000. And I don’t seem to be able to get a VPN log as it appears blank.
Yes, done it today. Downgrade didn’t do anything for VPN speeds. Speeds are still horrible. I get 3x speeds with NordVPN.
There seems to be a latency issue somewheres. I’ll try playing around with mtu settings tomorrow to see if I can get anything better. I tried pulling a log and it didn’t show any data so I’m not sure why but being remote is a pain playing with the setting on the phone.
I just tested 4.7.4 beta firmware and the slow wifi speed on 5ghz is still a problem.... Maybe in the release firmware it will be solved? Still using 4.6.2 or the dev firmware from this thread.
I’ve tested it on iPhone 13. The speeds are very erratic. When I do speed tests it sometimes goes to 60 then back to 20 in the same test. Speed tests finish anywhere between 20-60. And upload speeds can be in single digits.
For client I was using mt3000 but because it’s stable with NordVPN I don’t want to mess anything at this time as I’m still a week away before I get back home.
But I am was able to get speeds better after firmware but only they’re very unstable at this time. I’ll play around with it through iPhone and see if there is anything else I can do. I’ll test different mtu settings.
No @Renato, it's not normal, since there's no issue on firmware 4.6.2 and it only happens on Mt6000. I tested several new generation routers from Huawei and xiaomi, I have no problem with these.
If you read carefully the thread you can see these issues appears on Huawei P30 Pro (another thread on this forum have issues on Huawei P20 as well). My device is from 2019. It old but not so old. Amazon echo show is from 2020 so no so old. Both are Android based. It also happens with GL-AR750s-ext.. A device from GL. So it's a issue and @bruce already knows how to fix. Hope this can solved in the next release.
@raphamotta this may or may not be firmware. If you have chosen DFS channels for your WIFI, this will absolutely happen as when the router detects any interference on the DFS channels it will reduce the channel width. That is normal for WIFI 6 as it is a regulatory function. If you are using non-DFS channels (varies by country), then the channel width should be stable over time. I am using a non-DFS channel (like 36, 40, 44 or 48) in my location, and I can run 160 MHz for months which is 2.4 Gbps for the connection speed on the air interface. I am using my own OpenWRT build for my GL-MT6000 these days but the functionality is the same on the GLI builds.
Which bands are you using and are they non-DFS bands in your location? If you don't know, you need to do a little homework and find out. Take care!
@bruce not sure what your firmware update is doing. The latest opensource drivers are from August 23, 2024. But as in my text, this appears to be the correct functionality for a DFS channel. If the channels selected are non-DFS it requires more investigation. @raphamotta should provide country code, and 5GHz wireless options. With that info it would be easy to troubleshoot this.
I'm using channel 36, a non DFS channel, and I didn't change my country code in Flint 2. I just checked and it's US.
It's indeed a firmware issue, since the issue only happens on firmware 4.6.4 and above. I didn't have the same issue in others router using the same specs.
I am using a vanilla OpenWRT build without issue on a non-DFS channel. Currently on 24.10 rc5 which like rc4 seems really stable. The reason why I switched to my own OpenWRT builds is because of poor IPv6 support on the GLI builds for IPv6 tunneling protocols. But the wireless performance was actually OK in my experience with the GLI builds.
Have you considered using an OpenWRT build?
Can you take a screenshot of your settings from LUCI (Advanced Settings)?
