Thank you for your speedy reply. Here is the output you requested.

acer-wireless on an Ideapad, eh? Please run:

lsmod | grep acer

Is the module acer-wmi loaded? If so, that's our offender. Let's remove it:

sudo modprobe -r acer-wmi
sudo rfkill unblock all

Now does your wireless work? If so,let's blacklist it so it doesn't come back again:

sudo su
echo "blacklist acer-wmi" >> /etc/modprobe.d/blacklist.conf
exit

Post back your result so the searchers will learn.

OMG it worked ...this disabled the offending driver which I believe is the default for ubuntu. This allowed the process to connect and allow me to connect to the router. Did full restart and system automatically reconnected with router.

Thank you so much

Where can I learn more about ubuntu and coding so I can help users in the future?

I'm glad it's working! Have fun!

I am sure there are books but I just read the forums and examine my test system, an older laptop with nothing too crucial on it. If I make a mistake, I can reinstall or otherwise without losing my essential files.

Broward County?? I hearda that place. I spent quite a few years in Boca before I moved to SC.

Would you please use thread tools at the top to Mark Solved?

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?

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

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:

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:

nm-tool

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

[bingtian]

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.

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.
