I have a Dell Inspiron Mini running Windows XP Home, and a Verizon 4G MiFi wireless modem. On Sunday night I was able to connect to the Internet, on Monday morning I couldn't. The modem is showing 5 bars. My Wireless Card Utility also has 5 bars and says "Status: Connected; Signal: Excellent". I did some testing on the modem - restarted it, removed/replaced the battery - no change. My smartphone can connect to the Internet using the modem with no problem which makes me think the problem is in the laptop. When I run Software Diagnostics in the wireless utility it says I failed the Association Test. Can anyone tell me how to fix that? And how it might have just spontaneously changed between Sunday night and Monday morning?
Please follow the below mentioned steps that can fix the issue:-
1. Check if the 'internet' light is lit on the modem and router.
2. Tap F8 repeatedly as soon as you switch on your system to go Advanced Boot Options. From there you need to select “Safe Mode with Networking”. Check if the internet is working there or not.
3. Would also recommend you to do a system restore and take the system to a prior date when it was working fine. At times it can be due to the updates not being properly installed on the system. To perform System Restore click on the link below:-
