Today I connected to my friend's wifi and tried to troubleshooting my old problem
For the last trick I went for bios update and hdd regenerator. I have vostro 3300 and update it to a10 and a12 from dell.com and my product number and nothing's wrong I even restart 2 or 3 times and everything was fine.
After I came home I try to connect to my home wifi and windows 8.1 updated says that (cannot connect to the network).
I almost try everything like
- driver update or downgrade
- windows repair
- normal nod32 scan
- switch to local account
- uninstalling hdd regenerator, dell wifi controller, some other programs
- uninstall and reinstall wifi driver
- disabling Bluetooth driver
- disabling virtual box network adapter and remove it from wifi
- test in safe mode
- and know I'm scanning under safe mode with nod 32 (eset)
Suggest me what to do.
UPDATE
I can see the wifi's but it has low rate of refresh.
I can put wifi pass and windows try to connect but it ends on authentication.
I put the correct password and I'm 100% sure.
I test it with my phone wifi it cannot connect to my phone wifi either so it's not my modem
exact errors:
- most of the time after I put password it says verifying and connecting and then says can't connect to this network
- sometimes it shows connecting and even connected and wifi signal is full (it is half always) and then it disconnects
- after try to reconnect again it shows checking network requirements and then show can't connect to this network
I try to forget it and doing the same things showing the same result.
