Killer E2205 NIC

[Tristan_Cormier]

Hello,

I am experiencing issues with my Killer Network E2205 NIC (Atheros QCA8172) on Ubuntu Vivid Vervet (15.04) and would greatly appreciate any help in resolving them.
The wireless-info text dump is attached within.

Thank you for your valuable time and consideration.


EDIT: The problem was resolved thanks to chili555's suggestion.

I'm still not able to connect to the internet or my router via the LAN. Any help would be greatly appreciated.

I'm not sure if I can help much, but I think others might be able to help more readily if you include the output of the wireless-info script from this pinned thread.

Specifically, these commands:

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

I've updated my original post with the wireless-info dump file. Thank you.

It looks like you are well and truly connected to me:

Are you able to ping?

ping -c3 192.168.1.1
ping -c3 8.8.8.8
ping -c3 www.ubuntu.com

I am able to ping my own addresses and my ISP's but nothing else.
www.google.com, www.ubuntu.com return unknown host errors.

Could it be a problem with my ISP? Everything works fine on my Windows 10 partition.

It may be a DNS issue. According to your wireless-info, you have:

IP4.DNS[1]: 207.134.193.189
IP4.DNS[2]: 8.8.8.8
IP4.DNS[3]: 192.168.1.1

Are those numbers you plugged in to Network Manager? How do they correspond to the same data on your Windows partition? No typos??

IPv4 DNS servers are the same on Windows. I don't know what the hell is going on.

I have finally been able to resolve my problem by manually setting my DNS servers under the Network Manager.
Thank you very, very much for your valuable time and continued support.

EDIT: It turns out I was only able to connect to the internet for roughly 30 seconds, before experiencing issues again. Could it be my ISP that is at fault here?
How do I go about asking them for help, knowing that they have no trained technician and will likely be unable to understand even what an IP address is?

[chili555]

I'd try setting my DNS nameservers to:

8.8.8.8
192.168.1.1

I suggest you also try:

sudo ip route delete 169.254.0.0/24 dev eth0

Then try again.

I doubt it is your ISP. All your ISP sees at its end is the router. By the way, most run a very small version of Linux.
