I've seen that other people have had the same issue that I have (in other versions) but the answers that they've gotten haven't worked for me. I have a dual boot with windows 10 and Ubuntu 22.04, when I'm using windows all seems to be good and the connection works fine and in others devices it works too. The problem is on Ubuntu, because I have high spikes on my latency, as we can see in this image. However when I ping my default gateway the response is less than 1ms, so the problem is not with the LAN. The spikes occur between 5 and 20 seconds, for example the pings are usually from 9ms to 12ms and suddenly it jumps to 300ms.
This is my ifconfig and my iwconfig the network adapter, that is RTL8192EE PCIe Wireless Network Adapter. The adapter only works on the 2.4 Hz bandwidth. I tried putting the Power Management:off with sudo iwconfig wlp6s0 power off
, i also tried apt install --reinstall linux-firmware
because I read that worked for other people, adding others DNS directions

This is not a router or interference issue because all the other devices works properly. I tried more things but they were some many that I don't remember.
I more information is necessary I'll upload without any problem. This is the last thing that I'll try to do because I didn't find the solution in any other place. Thank in advance to all.
