Hi, Im kind of getting crazy about this...First of all sorry for my english, I will try my best to explain my problem. I read a looot of topics about "Limited connection", no internet connection..but I cant solve my problem

My GF owns a Toshiba Laptop (Satellite S855), she connects to the internet trough a 4G USB Modem, everything worked fine until somedays ago a friend of us uninstall avast (that was the antivirus she used) and turn on windows defender and made something with the firewall, since that day when we connect the Modem it doesnt have any data traffic, it connects but there 0 packets send 0 recieve... At first, we tough it was a MODEM problem, so we try to connect it to a wifi connection and nothing. I recieve the message that the connection is limited.

Well thats the problem and I cant do anything, I try to restore it, but by some reason I can only restore it to the point where avast was uninstalled it and is still not working. I have 2 restore point before that, but none of them works, I recieve the message that the restore was unsucessfull.

I check the drivers, but I cant find the drivers for the pc, and, as I dont have internet connection, cant reinstall the drivers in the pc, so I think I have to put the drivers form an external PC or something

I dont know what else to do, honestly...if you can help me with something, I will really appreciate it, please. Have a great day

Hi

See if avast was completely uninstalled especially the firewall

See if you can temporally disable the windows firewall

See if you connect via wireless at a location with free wifi or a friend house

Running with no firewall is dangerous so do not leave firewall off for long

If avast is current version (paid for or free) I would re install it once the USB 4G is working again.

Confirm device manager shows the USB 4G card is recognised & working
Drivers are probably on USB 4G dongle (flash memory pretending to be a small cd )

Microsoft fixit solutions may help
Ensure you only download from Microsoft web site

Hi, thanks for your answers...well I know is not the firewa1st I restored defaults, and nothing, after I turn it off and still anything.

Second, with avast uninstall it start the problem, then I restore it to the point when Avast was still ON, and the problem persists.

I tryied toconnect with Ethernet, I tried WiFi, I tried to put another modems on it...and none of them works, WiFi doent have internet connection but it has network connection. Modems dont show any data traffic.

Probably I have to install again the drivers, I download all of them from Toshiba website??

BTW, maybe is releavent or not, but I cant play PES 2014 in the PC after all that s#1@ either...it says I have a problem with RLD.DLL..maybe is the same, or maybe another problem, but I want to fix the internet connection first.

I will try drivers, and please if you have any other solutions I will really appreciate it. Thanls

Try to use "system restore" and point the date to when it was working or when there is a date available that was working and it might fix other wise like the other guy said get the driver from the manufacturer website.

Right Click the Internet Access icon in the taskbar, and click Troubleshoot problems, let the process go on, and inform what does Window say once it is finished diagnosing...

Sounds like the firewall was enabled with maximum security enabled. This would block all incoming and outgoing internet connections.
To check if this is the case:
start cmd.exe as a admin (windows key+x then type A)
net.exe stop "windows firewall"
ipconfig.exe /renew

at this point, check to see if your intenet access is restored (try a browser)

if it does work then you just need to configure your firewall. if it does not work
type
ipconfig.exe
and post the results

note: this also assumes you don't have two firewalls running on your machine now.
