[GMod] Cannot join any server ("Retrieving server info...") - Help

Hello everyone Until today, I never had any problems joining any servers on GMod. But since today, whenever I try to join a server, I can't get past [B]"Retrieving server info..."[/B] and can't play on any server anymore. I tried to join several different servers. It gets stuck at "Retrieving server info..." for a while (maybe 10 - 15 minutes?) and then disconnects, saying I timed out. Now the thing is that my ISP changed yesterday. GMod was working with the old router yesterday (while already connected to the new ISP), but I got a new router today from the new ISP and it stopped working after switching out the old router with the new one. I set up port forwarding for my new router (a [I]Fritz!Box 7490[/I]), but it doesn't work. I also disabled my firewall and tried to verify game cache. Additonally, I downloaded and installed Garry's Mod on my laptop today to check whether it's a problem with my desktop, but the problem occurs on both computers. Maybe I should also mention that I'm now using a wireless connection while previously (until yesterday), it wasn't wireless. Other Steam games work perfectly fine in mulitplayer, it's just GMod where I can't join servers anymore. Here's my desktop's specs just in case: [I]Windows 8.1 i7 4770k 16 GB 2x GTX 770[/I] I would be very glad if someone has any advice for what I could do to fix this or to help me find out the cause of the problem. Thanks a lot.

Can you try wired connection?

[QUOTE=Robotboy655;49657235]Can you try wired connection?[/QUOTE] Unfortunately not. The router is at a new location and the old wire is too short to reach it, although I'm planning to buy a longer wire to connect my computer. But I don't know if that would fix the problem. [editline]2nd February 2016[/editline] Edit: I will try to plug in my laptop and see if it changes anything. [editline]2nd February 2016[/editline] Edit2: Okay, I tried using an ethernet cable for my laptop and it works, so there seems to be a problem with the wireless connection. Any suggestions on how to fix it?

Your wireless connection can't handle it then.

[/QUOTE] [QUOTE=http://www.fritzbox.com.au/product-fritz-wlan7490.html#1] Wireless LAN Functions: Wireless radio networks according to 802.11ac (up to 1300 Mbit/s*, 5 GHz band), and 802.11n (up to 450 Mbit/s*, 2.4 GHz), downward compatible to wireless standards 802.11g, b and a [/QUOTE] Considering this is a relatively decent router and connecting to servers in other games, I don't think that it's the wireless connection per say. I could be wrong. [QUOTE=Tsumugii;49657214]Now the thing is that my ISP changed yesterday.[/QUOTE] This is key. Can you post your port forwarding configuration?

You could try that, if you need help on how to do it just ask me.

Oh sorry for the late reply, I should have posted earlier that my problem is solved now and I can join servers again. Thanks a lot for your replies. What helped was plugging in a wire for my connection permanently because apparently, the WLAN in my home isn't strong enough for playing GMod (but strong enough to access the internet for other things weirdly). 4 out of 5 signal bars.
