Approximately 4 or 5 days ago, the connection to the internet was not working. I am using cable. The internet stopped working. I played around with different lan settings and other things and I was able to get the internet up and running, but now my problem is and I have tried most of the solutions given. I have searched for resolutions on my own and tried them without any avail.

This is the error that I keep getting when I try to sign in.
The first error code: 80048820
The extended error code: 8004840f

Now I have adjusted my clock because it was way off, and tried the solutions I was able to find, without any luck.. I have not changed anything, I have had no problems like this before, so I am at a loss as to what could have happened.

PLEASE HELP, I BEG OF YOU ALL. LOL
NOT NEW AT COMPUTERS BUT I HAVE TRIED ON MY OWN, NOW I NEED REINFORCEMENT... LOL

Joe, Thanks in advance...

Hello There,
Possible Cause of Code 80048820
There are a variety of causes of this error:

1) Incorrect Proxy Setting for Internet Explorer.

2) softpub.dll may have become unregistered.

3) Your system clock may be showing an incorrect time - or date! (Wrong time is the most likely cause of 80048820).

4) Firewall problems. Particularly with Netgear.

**********************************
The Solutions to MSN Error Code 80048820
Internet Explorer - Try removing the tick next to Internet Explorer 'Proxy server' settings, instead, go with the 'Automatically detect settings'.

1) Launch Internet Explorer, click Tools and then click Internet Options.
From the Internet Options dialog box, go to the Connections tab.
Click LAN Setting. Un check the Use a proxy server for your LAN (These settings will not apply to dial-up or VPN connections) checkbox. Finally positively tick: 'Automatically detect settings'.

2) Register softpub.dll.

Click Start (Button), and then click Run, type regsvr32 softpub.dll. Restart MSN Messenger. See also Error code 81000314

3) If necessary, logon as a local administrator and set the computer's clock to the correct date and time. (Check on the internet if possible.)

4) Turn off the firewall temporarily. Check firewall settings such as Norton: "Block access to secure sites". If this cures the problem, make sure that Microsoft's MSN Messenger is allowed full access through your firewall.

NetGear problem, but also with some other routers
a) Enter IP address 192.168.0.1 in your browser's address bar.
b) Log on with ISP user name and password.
c) Enter Admin, password
d) Navigate to advanced menu, WAN set-up
e) Change MTU size to 1400

5) Try a password of no more than 8 characters.

6) If you are using IE 7.0 check the SSL Settings. Internet options advanced (Tab) scroll down to the bottom. Security section. Tick 'Use ssl 2.0'.

7) One of the simplest ways of curing MSN error 80048820 is to unplug, or restart your modem. This is particularly effective for cable modems.

8) We should have tried this solution before; check that the MSN site is 'up' 'available'. However, even if the site is down, you don't usually get error code 80048820.

8a) As a variation, of checking online, you could try phoning your local Microsoft Support office. Local area numbers available from Microsoft Help and Support.

9) Have you just installed any anti-virus software? Did the anti-virus software just make a big update? Try disabling and see if that cures the error.

10) A drastic solution is to try uninstalling MSN Messenger version 8.0 or 7.5 and install Microsoft MSN version 7.0.

Agree with everything above and if still having issue, would recommend uninstalling MSN and then reinstall the software as there may have been some settings you adjusted did not take with MSN - so reinstalling would be a good option
