Slow Wifi connection on laptop with Ubuntu 24.04.2 LTS, RTL8723BE

Ubuntu Version: Ubuntu 24.04.2 LTS

Desktop Environment (if applicable):

Problem Description:

Sometimes the wifi connection slows down severely, so slow that it is impossible to get anything done. This happens at random accordingly to no pattern that I can tell.
This problem started sometime after I moved, but I don’t know exactly when or if this is relevant. It has persisted for many months but seems to be happening more frequently recently, frequently enough to be really bothersome.

Using ping I have determined that the system is having trouble communicating with the wireless router, though the packet loss rate is not 100%.

This problem does not happen with other devices. I can be streaming video on them while simultaneously my Ubuntu laptop’s Internet is basically useless.

What I’ve Tried:

Following online advice, I disabled wifi power saving by setting “wifi.powersave = 2” in /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf. At first this seemed to resolve the issue, but a couple of weeks later it has started again.

Also, following the advice at HardwareSupportComponentsWirelessNetworkCardsRealTek - Community Help Wiki, I created a file /etc/modprobe.d/rtl8723be.conf with the contents “options rtl8723be msi=1 ips=0”. This did not seem to have an effect, so I undid this change.


Do you have other computers on this same network, which experience the same problem? Or is it only your Ubuntu laptop?

It is only my Ubuntu laptop.
