hello,
I am unable to connect to my home WiFi network. I click on connect to my WiFi it asks for password ,I have put correct password in the password dialog…after 5 to 6 second it again asks for password and I am not connecting to my wifi.
I can’t get what is the problem. other devices like phone tablet working fine with same wifi network. Even windows 10 from same laptop working well. Please guide.
I have Dell Inspiron11- 3148 2in1 laptop with BCM 43xx chipset.
You likely need the b43 firmware
sudo /usr/sbin/install_bcm43xx_firmware
I have BCM43xx firmware installed already. its detecting wifi but continuously keep asking password to connect the network. i have deleted existing network setting from network and again configured it, but still same problem persist.
it continuously asking to enter password. i can connect my android phone and windows 10 with WIFI.
please guide
Which GUI are you using? – KDE, Gnome, Xfce, something else?
Which Network Manager are you using?
I am using KDE.
Let us see
/sbin/lspci -nnk
I do not want to hijack this thread, but I have the same problem: OpenSuSE 13.1 on HP Pavilion DV8000 + Netgear WNDR4500 wireless router.
Relevant output lspci -nnk
06:02.0 Network controller [0280]: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] (rev 02)

Kernel driver in use: b43-pci-bridge
Kernel modules: ssb
Please deal with the OP’s problem; I’ll follow this thread for suggestions.
I don’t know if the problem is the driver if the AP is recognized and it’s prompting for credentials.
I’d suggest taking a closer look at the security configuration… ie
Also,
I don’t see that the OP described whether he’s using NM (generally that should be the case) or Wicked.

This is how I stopped the repetitive prompting for login and password.
The Netgear router I have can be accessed by entering 192.168.1.1 in a browser. The login and password for the router’s firmware configuration app are NOT the same as provided in the Netgear documentation for enabling the router network. I used “admin” and “password” respectively. In the “Wireless” section I found a “pass phrase” that is some 40 alphanumeric characters. This is what I needed to set up an HP wireless printer. When I got the prompt for credentials when starting wireless, I entered this 40-character pass phrase INSTEAD of the password. That started the wireless and stopped the login menu from popping up over and over again.
It appears that when using the Netgear router with Windows or Mac OS X, sending the human intelligible password lets the router parse its lengthier gibberish pass phrase. Maybe there is a way to get Linux to do the same?
BTW I am still not able to communicate wirelessly. I need an ethernet cable between the laptop and the router in order to get the procedure I described above to work. Without this connection, the browser cannot make the connection.
Given the following network adapter:

andgiven a WLAN with WPA-PSK security (WPA & WPA2 Personal)
andinfrastructure WLAN mode
anda hexadecimal WLAN password with 10 hexadecimal characters
andautomatic IPv4 and IPv6 WLAN methods
andautomatic connection if and when the WLAN is available
andcorrectly functioning kwalletd5-5.16.0-3.1.x86_64 with kwalletmanager-15.04.3-3.4.x86_64;
I have no issues connecting to an AVM Fritz!box WLAN.
But, I have had issues in the past with anything other than hexadecimal WLAN passwords.
And, I’ve noticed that the Plasma5 KWallet is:(a): needed
(b): fussy – the migration from Plasma4 (openSUSE 13.2) was not clean – I had to delete and recreate.
i have tried these methods too but not working for me. it still asks password n not connecting to wifi 
Post the result of
/sbin/lspci -nnk
While logged into your router using a web browser, change the 40 character pass phrase with a simple 10 character pass phrase. Use something simple while testing and learning about your device, like ten ones. You can change this later when you fully understand what is going on.
You didn’t mention what type of encryption is being used. If specified, note what it is. AFAIK all modern devices suggest using AES, although stronger SHA might also be usable.
When you set up your Client machine, what are you using… The default Wicked or Network Manager? The former is OK if your machine is a non-portable machine while Network Manager is highly preferred if you move from one network to another.
Is your Access Point discovered automatically by your Client?
Configure the correct password, and depending on your connection manager set the correct encryption algorithm.
Attempt to connect.
If you are unable to connect, then you can inspect your system journal but you might get more useful information by installing Wireshark and doing a capture during the connection process.
