Thanks for quick response. It did not work.
I tried the codes that you recommended.
sudo apt-get remove --purge bcmwl-kernel-source sudo apt-get install linux-firmware-nonfree sudo modprobe b43
this is what I got.

Please Help.

Sir or madam: I am answering in your own thread and not here. I am not going to answer every question twice and you needn't ask twice.

Hi, chili555,

I have a very strange problem with my acer aspire 3750G. I have two routers at home, it can connect to one router (belkin), but not the other (huawei), could you please help me see if there's anything wrong with my wireless?

Code:

bingtian@aspire3750G:~$ dmesg | grep iwl
bingtian@aspire3750G:~$ rfkill list all
0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: acer-wireless: Wireless LAN
    Soft blocked: no
    Hard blocked: no
2: acer-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
3: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

Does the sequence matter? original order was 1,2,0,3, but i did some modprobe, and but acer-wsi in blacklist once.

Code:

bingtian@aspire3750G:~$ lsmod | grep acer
acer_wmi               28418  0
sparse_keymap          13890  1 acer_wmi

bingtian@aspire3750G:~$ dmesg | grep ath

Is there any problem? Thank you. I can provide more info on how the two routers are configured. Thanks.

I can provide more info on how the two routers are configured.

Please do. You might try a temporary driver parameter:

Code:

sudo modprobe -r ath9k
sudo modprobe ath9k btcoex_enable=1

If it helps, we can write one quick file to make it persistent.

Please post:

Code:

nm-tool

Tell us which two access points you are trying to connect to.

**bingtian** · February 21st, 2013

Hi, chili,

Thank you so much for your reply, and sorry for the late reply as now both networks do not work for my ubuntu, so I come up online from the other computer.

The two networks are configured like this: one network is a subnet of the other. I name the larger one CO and the subnet ES, they are connected through home plug: ES's uplink is from CO LAN port. CO is configured with 192.168.64.* (gateway at 192.168.64.1, mask 255.255.240.0), ES is configured with 192.168.66.* (gateway at 192.168.66.1, mask 255.255.255.0). So the gateway for ES router is set at 192.168.64.1. This configuration works, as my notebook connect to ES in the bedroom and connects to CO at the living room.

So I paste the outcome after doing "modprobe -r ath9k" and "modprobe ath9k btcoex_enable=1", for CO first, then ES.

Code:

I don't think you have a wireless card problem at all. I think you have a gateway, subnet, too-many-routers problem. I don't know how to fix this:

wlan0 Link encap:Ethernet HWaddr 88:9f:fa:a2:ac:b1
inet addr:192.168.64.31 Bcast:192.168.79.255 Mask:255.255.240.0
inet6 addr: fe80::8a9f:faff:fea2:acb1/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

It may be solvable and it may be fine but I just am inexperienced in such complications. I suggest you start your own new thread and refer to your setup in detail and ask for an answer. I don't have it.

I wish I could be of more help.

**bingtian** · February 22nd, 2013

Hi, chili, thank you for your answer, I suspect it's the router problem too, but windows and androids are fine with the setting since Bcast:192.168.79.255 (11000000.10101000.01001111.11111111) & Mask:255.255.240.0 (11111111.11111111.11110000.00000000) = subnet:192.168.64.0 (11000000.10101000.01000000.0)

Hi, I have problem with my wifi connection too. When I try to connect to my wifi, it writes: "Wireless connection established", but when I try to load a page in default browser, it says: "Server not found".
I'm using Xubuntu 12.10 and before i had installed Windows 8 and the wifi worked fine.
(I have Asus-X201E-kx006h)
