#StackBounty: #wireless #network-manager #internet #17.04 Can't connect to certain wifi network or if connects then internet is una…

Bounty: 100

After cleanly dual booting my new Dell Vostro 3568 with Windows 10 & Ubuntu 17.04, I am facing this issue. It happens in both the partitions.
I have referred following threads & others as well, but no luck:

Have tried to reinstall all the Dell drivers from Windows partition, but the issue persists. Basically my PC easily connects to most of the wifi networks, but it faces problems with certain network, which is a leased line and connected to a Ruckus router [with/without firewall].

Here is the pastebin output, which is derived from this forum link. I am able to connect with “AAHLAAD_AirtelBB” (as seen in pastebin), but unable to connect with “AAHLAAD_Production”. Reinstalling (without uninstalling) the network manager didn’t help.

Kindly help!

Update (12-Jun-2017): Though I fixed the wifi connection issue (see my answer), the internet connection issue is still not fixed. I even tried the solution described in this answer as well, but no luck. The problem still persists, where the internet works fine for less than a minute and then it doesn’t work at all. The wifi remains connected though.

Bounty (28-Aug-2017): Had posted this problem in Ubuntu forums as well, but no luck so far. Hence starting a bounty.
Ubuntu Wifi connected but no internet (internet remains for short time)

#StackBounty: #16.04 #networking #network-manager #wpa2 Can't connect to WPA2 Enterprise PEAP network

Bounty: 100

I know there are about a dozen other questions like this, but so far none have helped me.

My school uses a WPA2 Enterprise PEAP/MSCHAPv2 network without a cert(which I determined from a windows laptop that connected without an issue). I’m trying to connect with my Ubuntu 16.04 LTS machine (which is pretty much a fresh installation).

Unfortunately, it is unsuccessful. It tries to connect for a while, then brings up a username/password reentry dialogue. If you hit submit on this, it simply fails again and brings it back up.

The following shows the settings and the message that keeps coming up:
enter image description here

The following is the /etc/NetworkManager/system-connections/ entry:

I’ve read in many places that adding system-ca-certs=false fixes it, but that didn’t work. I also tried adding the domain Domainusername but that didn’t work. I’ve tried everything here and in many other posts. Not sure what to do, I’m new to Linux. Any help is greatly apreciated, if there is some other info I should include please let me know. Thanks!

note: I can’t obtain a certificate because I seriously doubt I’ll be able to contact someone who’d give me one (as I am a student). Not to mention, I don’t think they’d be familiar with a Linux based system as the school issued computers are Windows 10.

edit:
I read a lot that the problem was caused by Wpasupplicant 2.4. So, I tried downgrading to 2.1. This actually worked* when I restarted, but after a while disconnected and I couldn’t get it to connect again. I even tried reinstalling wpasupplicant 2.1 but it still wouldn’t connect. I’m not sure what all that implies, but at least I know that my laptop is capable of connecting to this network and I have the correct security settings/credentials.

*= the connection lasted for aprox. 10 minutes, and was much slower then it should’ve been. My windows laptop got 60 mbps download while this one got only 15 mbps. Granted however, Windows laptop is 2-3 years newer.

edit 2: My network card in the Ubuntu machine is a Centrino n 1000 Condor Peak from Intel. I’ll gather more information on it when I get a chance.

#StackBounty: #16.04 #networking #network-manager #wpa2 Can't connect to WPA2 Enterprise PEAP network

Bounty: 100

I know there are about a dozen other questions like this, but so far none have helped me.

My school uses a WPA2 Enterprise PEAP/MSCHAPv2 network without a cert(which I determined from a windows laptop that connected without an issue). I’m trying to connect with my Ubuntu 16.04 LTS machine (which is pretty much a fresh installation).

Unfortunately, it is unsuccessful. It tries to connect for a while, then brings up a username/password reentry dialogue. If you hit submit on this, it simply fails again and brings it back up.

The following shows the settings and the message that keeps coming up:
enter image description here

The following is the /etc/NetworkManager/system-connections/ entry:

phase2-auth=mschapv2

[ipv4]

[ipv6]
addr-gen-mode=stable-privacy
dns-search=
method=auto

I’ve read in many places that adding system-ca-certs=false fixes it, but that didn’t work. I also tried adding the domain Domainusername but that didn’t work. I’ve tried everything here and in many other posts. Not sure what to do, I’m new to Linux. Any help is greatly apreciated, if there is some other info I should include please let me know. Thanks!

note: I can’t obtain a certificate because I seriously doubt I’ll be able to contact someone who’d give me one (as I am a student). Not to mention, I don’t think they’d be familiar with a Linux based system as the school issued computers are Windows 10.

edit:
I read a lot that the problem was caused by Wpasupplicant 2.4. So, I tried downgrading to 2.1. This actually worked* when I restarted, but after a while disconnected and I couldn’t get it to connect again. I even tried reinstalling wpasupplicant 2.1 but it still wouldn’t connect. I’m not sure what all that implies, but at least I know that my laptop is capable of connecting to this network and I have the correct security settings/credentials.

*= the connection lasted for aprox. 10 minutes, and was much slower then it should’ve been. My windows laptop got 60 mbps download while this one got only 15 mbps. Granted however, Windows laptop is 2-3 years newer.

edit 2: My network card in the Ubuntu machine is a Centrino n 1000 Condor Peak from Intel. I’ll gather more information on it when I get a chance.
