Cellular Disconnected


I have a cellular modem in my Dell Precision 3520. I used it Friday without any problems at all. Today, as I'm at work, I cannot connect to AT&T's cellular network.

When I click the network icon in the system tray, it shows my cellular connection as "AT&T (HSPA)" and then reads "Disconnected" underneath it. It shows 5 bars. If I open network properties and try to troubleshoot the adapter, it gives me a SIM2 error that says I need to enter a PIN code (there is no PIN code on the SIM card, but just for troubleshooting purposes I added one, still got the same error, and then ultimately removed it again).

Things I have tried so far:

• Toggling cellular on/off
• Rebooted computer (several times)
• Uninstalled and reinstalled the driver (twice)
• System restore to the point where it was working the other day
• Ejecting the SIM card and reinserting it
• Verifying that data is turned on with my AT&T count
• Enabling/disabling PIN code
• Resetting network settings via command prompt
• Creating a new APN (with phone, NXTGENPHONE, etc.)

Any tips?

 

No internet access over cellular while Ethernet is plugged in

Hi,

I am trying to use cellular and Ethernet networks at the same time. However, my Ethernet does not provide internet access, only network storage access, but it stops the cellular internet as soon as I plug in my Ethernet cable

Is there any ways I can still use cellular data while I am accessing my network storage on Ethernet?

Regards,

Jack

 

IP configuration not valid - interference from ethernet adapter?

Solution 1: No Internet Access In Windows 8.1or Windows 10

Step 1:

Go to Device Manager → Network adapters.
Step 2:

Expand it (Network adapters).


Step 3:

Select your network adapter


Step 4:

Right click on your wireless network adapter or Ethernet adapter and then tap “Update Driver Software”.
(in this case your network adopter is Ethernet adopter so tap your Ethernet adapter)
Step 5:

Now on a new window you will need to click on “Browse my computer for driver software”.




Step 6:

Then select “Let me pick from a list of device drivers on my computer”.



Step 7:

Now choose the “Manufacturer’s drivers” from the list of two and then click next.



Step 8:

After the completion of the process just restart your PC and check if the problem is solved or not. If not, goto solution 2.



Solution 2: No Internet Access In Windows 8.1,windows10

Step 1:

Open command prompt.
Step 2:

Just go on hitting the enter after typing the each command.
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disable
netsh int tcp set global rss=enabled
Step 3:

Now to check if the settings are disabled type:
netsh int tcp show global
then hit enter.
Step 4:

Now the thing left is just rebooting your system and just check if the problem is solved or not and just give feedback.*chuckle*Thumbs
