Solved Steam error -105

[behindyouu]

Hello, since yesterday I am getting this (Steam error -105) error and it says " Unable to connect to server. Server may be offline or you may not be connected to the internet." That error shows for every tab I click (market, profile etc.), and alos I cant even access the steam website or the forums. I can play online but I cannot trade.

Here's what I've tried.

• 
  Restarting Steam/pc

I had that once and these steps fixed it for me

Ok, so I am at this part, "Then, launch Steam.exe from within the Steam installation folder, and not from a pre-existing shortcut," but when I click Steam.exe it says, " Steam needs to be online to update. Please confirm your network connection settings and try again."

Also, I cannot access any website related to steam.

 

[Dude]

Try right clicking it and run as administrator. Also make sure your firewall isn't blocking it.

 

[behindyouu]

Tired it. Disabled Avast and windows firewall plus ran as admin.

 

[Dude]

I would uninstall steam, then re install. Make sure you back up your games first. Since you already tried disabling avast with no help it sounds like your steam install is corrupted.

How can I reinstall/download if I cant access the steam website?

 

[Dude]

Try another browser, which one are you using now?

 

[behindyouu]

Tried it with Firefox and Chrome and also tried in private browsing. I am using Chrome right now.

EDIT: restarting router did not fix.

 

[Dude]

Have you tried IE? I would suggest to uninstall AVAST completely, try using MSE and see if that helps.
Edit: you said it started yesterday, try a system restore prior to that time

[behindyouu]

I tried IE, but no luck. I uninstalled avast and installed MSE; same problem.

There is no restore point on the 15th, therefore I cannot restore.

EDIT: Never mind found it.

 

[behindyouu]

This message popped when the system restore completed.

 

[Dude]

Do you have an older restore point you can try?

 

[behindyouu]

No. But I think it might have to do something with my router because I can access steam website via LTE/4G.

 

[Dude]

You mentioned you restarted it earlier. Have you tried a factory reset with it

 

[behindyouu]

That might work, but it will take hours to set it up.

 

[Dude]

I will ask for some help from others with better networking skills.

 

[behindyouu]

Okay

Here is the router's model number : D-Link DIR-865L

Before we go fiddling with the router, let's make something perfectly clear:

Do you have administrative access and permissions to the router itself? If this is a router you personally own then this is a moot point, but we don't want you to get into trouble if this router is owned by (for example) your parents and you don't have permission to mess with it.

Also, to test if this a problem related to the router at all, let's see if we can isolate the problem:
A. Can you access the Steam website from any other computer(s) connected to the router in question?
B. Are you able to temporarily connect your computer to your internet connection directly without the router? If yes, can you access Steam's website without the router between you and the internet?

 

[behindyouu]

I have admin access and permission to the router. I don't own the router but I can change the settings.

A: No, I cannot access the steam website from any other computer.

B: No.


EDIT: The router is dual band, and for some reason I am not seeing the 5Ghz connection even though it is enabled in the settings.
