Slow and unstable wifi issue with fresh installation of Manjaro and particular wifi network

Support Network
1

I’m having issue of extremely slow internet issue with my college wifi. It works fine with ethernet but on using wifi it’s highly unstable like disconnects automatically and also speed and latency is very poor. With ethernet I’m getting around 100 Mbps while with wifi it’s around 2-5 Mbps and sometime even less. The same wifi working perfect when I boots into windows on same laptop so it’s not a hardware issue. I tried searching on many forums with the same issue but nothing seems to work.

This issue is only with my college wifi. On using my mobile data hotspot as wifi it works fine. FYI My college wifi needs a login portal on intranet.

On running below command

> inxi -F | grep iwlwifi
  Device-1: Intel Ice Lake-LP PCH CNVi WiFi driver: iwlwifi

System specs

> sudo inxi --admin --verbosity=7 --filter --no-host --width

  1. Please read the information behind this link. It will help you to post necessary information.
  1. Please press the three dots … below your post and then press the :pencil2:
  • If you give us information about your system, we can see what we’re talking about and make better suggestions.
  • You can do this by using inxi in a terminal or in console.
sudo inxi --admin --verbosity=7 --filter --no-host --width
  • Personally identifiable information such as serial numbers and MAC addresses are filtered out by this command
  • Presenting the information in this way allows everyone to be familiar with the format and quickly find the items they need without missing anything.
  1. Copy the output from inxi (including the command) and paste it into your post.
  • To make it more readable, add 3 backticks ``` on an extra line before and after the pasted text.

Have you already :mag: for your problem in the forum ? (Wisdom lies in reading :wink: )
