Problem Description:
I am trying to transfer 16GB video files from my Ubuntu 26.04 LTS laptop to a NAS server having both SMB & NFS enabled on both over my LAN. I am able to login into the NAS and connect using the “Files App” (Nautilus File Explorer); however, browsing or downloading or uploading is at a snails pace. I did not have this issue when 24.04 LTS was installed.
I receive a “connection timed out” error message.
Relevant System Information:
Dell XPS 13 9350 (2024 Model Year)
What I’ve Tried:
My Windows 11 Pro laptop has no issue transferring large video files and the same applies to my smartphone. Enabled SSH on the NAS and attempted to transfer files using “SCP command” on Terminal window but the results are the same. TCP Port 80 & TCP Port 443 are fine as I can web browse HTTP(S) traffic.
I suggest you use NFS. It’s a lot faster. You’ll need to configure the server side to allow the connection etc (See manufacturer’s manual etc)
The client side will be similar to this https://www.digitalocean.com/community/tutorials/how-to-set-up-an-nfs-mount-on-ubuntu-20-04
Scroll down to step 5 here. That’ll be something similar to be used on the Linux side. Windows has an NFS client that you can install and use
Thank-you for the suggestion. I have NFS enabled on my NAS and haven’t had any issues until I installed Ubuntu 26.04 LTS over Ubntu 24.04 LTS during the past month.
I did a distro upgrade as there are a few apps on Ubuntu 24.04 LTS that have registered purchases which I don’t want to start over or redo. I might consider a fresh install of Ubuntu 26.04 LTS if this is the only solution to remedy my LAN connection issues to my NAS.
26.04 LTS has WiFi 7 drivers that 24.04 LTS does not have. One main reason why 26.04 LTS was a long time coming. Networking wise in general is great except for the laptop with 26.04 LTS installed. As you can see from the screenshot, it’s a turtle of a transfer rate for large files.
That shouldn’t be necessary for keeping your registrations; usually one just needs to save some validation token and restore that after a fresh installation.
It’s not necessarily wrong to do the release upgrade as an early adopter, but it could be something worth investigating.
I’m suspecting that some driver component didn’t get upgraded properly or even might have been removed.
@peterwhite23 Well, I bit the bullet and did a fresh install of Ubuntu 26.04 LTS and it feels fresh but the transfer rate is not optimal as my r/x is only 5.0MB/s when I ought to be receive close to 25.0MB/s. The same can be said of the s/x. I’ll wait until the 1st point release is available in August and go from there.
Have you actually seen such data rates on the same machine, with another OS, in the same physical location? Because with WiFi people tend to expect the theoretical maximum advertised by the specs, which will never happen. I have no idea what’s a reasonable expectation with WiFi 7, though, because I haven’t kept track.
And what about the “Additional Drivers”? I don’t know if your device requires such for full performance.
Yes, I just reverted back to 24.04.4 LTS and I was receiving 30.0MB/s. Same machine, same location. Oh, I understand that the theoretical maximum throughput is the ceiling but other factors such as other electromagnetic interference, time of day and Internet traffic all factor in.
I need the full performance of my WiFi 7 network card because I am transferring large video files of 17GB. So, whatever maximum throughput I can get I would appreciate because it sucks just to wait for files to transfer.
I think you should consider filing a bug report, because it looks like a pretty clear regression to me. But it could just be some missing firmware; because of the ridiculous size of the linux-firmware package in 24.04, it was transformed into a metapackage, and maybe something fell by the wayside.
@peterwhite23 Or Canonical is intentionally throttling down the throughput capacity of Ubuntu 26.04 LTS until the 1st point release to “patchup the software bugs that obviously will appear” during a rollout of a new operating system. In any case whether the firmware or metapackage needs to be improved & updated, I am fine with Ubuntu 24.04.4 LTS as I have returned to the 30.0MB/s send/receive throughput before I upgraded to Ubuntu 26.04 LTS.
I really do miss the “Resource Monitor” on 26.04 LTS. That was probably one of the best improvements from 24.04 LTS asides from the new “Terminal Window”.
Those two things aren’t in any way connected. I don’t where you got that idea.
But if nobody reports the issue, it may never get fixed, or at least not before the point release. You’re effectively hoping that someone else steps on the same mine and does report it to the proper channels.
