Dear all,

I've been having severe internet speed problems with the biggest internet provider in the country I live.

After bringing it up to them they suggest to change the channel of the routers but nothing made it better.

I made this test. Could you please someone tell me if I configurate some things in a way to ameliorate my connection?

Changing the channel in your router most likely refers to your Wi-Fi, not the internet connection. What problems are you having exactly? Do wired client have those problems as well? Are the issues related to time of day, intermittent, or constant?

Hello Philip, sorry but I'm not very familiar with the forum and I thought I would have received a notification upon a reply to my post.

The problems I'm experiencing refer to the fact that it takes too much to upload a webpage, that watching videos on streaming is painful as the streaming stops often.

I use internet in the mornings and in the evenings and the problems are highly recurrent in the evenings.

I don't know about wired client.

I was wondering if there's anything in the setting of the router or the computer (a macbook) that I should change?

If you are behind a cable or dsl modem, you can login to its browser page and see what the signal levels are (if you post them here, we can help). Cable modems are often accessible via http://192.168.100.1

If there is a big difference between morning and afternoon, this could indicate congestion on the line in peak hours (after 5pm), this is usually an ISP issue. You'd have to run speed tests and let them know, but there is usually little they can do.

I was trying to eliminate the possibility of it being a WiFi issue, that is why I asked whether you have access to a wired client, something you can connect with a Cat5 ethernet cable directly to your modem. That way, you can determine whether it is an issue with the wireless portion of the connection, or your internet connection. It is only one test that can be done, but it would help if you talk to your ISP to convince them it is not a wireless issue on your end.
