Need help with Slow download speed on Manjaro

Support Network
1

I have a dual boot system and my download speed as shown below is slow compared to the other OS running on my system.
Arch shows near 100 download speed while Manjaro only shows around 19.

Bad timing?
Coincidence?

The software is nearly the same in Arch and Manjaro. The latter may be a little older at times.

Please format your inxi output as Preformatted text → </>
so it is readable and looks the same as what you saw in the terminal.

What mirrors do you use to download ?

I think I fixed the code issue.
Here is the mirrorlist but I am just doing a speedtest. What does the mirrors have to do with that?

Have you done anything to the network/driver configuration?

Is power saving on or off ?

In this directory I have 4 files:
blacklist.conf iwl.conf mhwd-gpu.conf nvidia.conf

What is contained in these was put there by instructions I either read from other posts or was told to put in there for reasons I don’t remember now.
blacklist.conf:

# Disable intel mei (including mei_watchdog).
blacklist intel_pmc_bxt
blacklist iTCO_vendor_support

# Do not load the 'iTCO_wdt' watchdog module on boot.
blacklist iTCO_wdt

iwl.conf:

ptions iwlwifi 11n_disable=1 swcrypto=0 bt_coex_active=0 power_save=0
options iwlmvm power_scheme=1
options iwlwifi d0i3_disable=1
options iwlwifi uapsd_disable=1
options iwlwifi lar_disable=1

mhwd-gpu.conf

The blacklist.conf is OK - watchdog is rarely needed for at desktop system.

I am fairly confident that your Arch system does not have the iwl.conf.

The first thing to do is to comment all lines in that file
Save the file
Unload iwlwifi
Load iwlwifi

Then test reconnect your network.

Well it looks like something in that file is the issue.
So should I try to figure out what is causing the issue or just move on?
I think I put all those lines in there trying to fix my problem I have with my bluetooth not working.
But that is another issue.
Thanks I will mark this solved.

I don’t know - you must have had your reasons to create it in the first place - and I have no idea what function the parameters have.

You can do a one at a time enable to see which one triggers the slow connection.

Personally I think that 11n_disable=1 may have something to do with it.

11

Yup.
This would mean you dont get ac or n … so you would be stuck on g maximum. Which has a bandwidth of 54 M in the absolute best of circumstances.

Also

This should only be used in certain situations, and only on kernels older than 5.4.
Even then - it is expected to negatively impact your throughput.
No idea why you would have this.

This might save a bit of power, but is expected to increase latency (‘ping’).

Note: It also makes no sense that you have some ‘power saving’ options set … but in other options you attempt to disable the cards power-saving features.

Finally this one

Would disable a regulatory domain logic. I see some very old reports of some people needing to rely on this for some reason or another, and no idea whether this ever applied to you, but I think it may have been removed back around kernel 5.4.

I don’t remember for sure but I think all of those things were suggested to me to help with my bluetooth issue with this network card. Since it didn’t get the bluetooth working I just left them all there.
