When 2 or more devices are connected to the wifi, the internet connection becomes very unstable and slow.
Some examples of what happens:
When only 2 devices are using wifi (for browsing), when loading a website, the website stays in blank for several seconds and then suddenly loads completely.
When many devices are using the internet, the website doesn't load at all.
When gaming, and with only 2 devices connected to the wifi, the ping constantly jumps to 300-1000ms.
The router has 2 wifi options, 2.4 GHz and 5 GHz, both are enabled. This is about the 2.4 GHz connection.
I have not tested this issue in the 5 GHz, since most devices in the house can't connect to 5 GHz.
This does not happens if connected with ethernet. Several computers are connected to the same router with ethernet, and do not experience this issue.
Internet speed with ethernet is about 100 Mpbs download and I think 50 Mpbs upload.
Internet speed with Wifi, about 10 m away from the router, is about 20 Mpbs download and 15 Mpbs upload.
The router model is Buffalo WZR-1750DHP
What could be causing this? How can I fix it?
