Wireless Network Connection - Annoying Problems

[amjjawad]

Hello everyone,

I have some annoying problems with my main PC. One of these problems I've been suffering from since I have installed Ubuntu 10.04 (Desktop 32-bit) is:

Connecting to Internet using my Wireless Network is a headache.

How is that? I'll explain.

Case1
Problem: Whenever I choose "Hibernate" sometimes and then turn my PC on, I lose the Wireless Connection.

Solution: Restart/Reboot my PC. Sometimes, I have to restart my Router and sometimes I have to reboot my PC more than once. Usually, once do the job.


Case2
Problem: Whenever I disconnect my Wireless Connection (regardless why I'm disconnecting it), I can not re-connect at all.

Solution: Restart/Reboot my PC. Sometimes, I have to restart my Router and sometimes I have to reboot my PC more than once. Usually, once do the job.

Case3
Problem: Whenever I restart my Router, I can't connect to it through the Wireless Connection.

Solution: Restart/Reboot my PC either once or more than one time.


Above are the main 3 scenarios I do have at the moment and I've chosen to live with it all that time but enough is enough.

Additional info that might help:
Network Card is: D-Link Airplus G Adapter
ADSL Router is: CableWireless

I'm sure there's another way much easier and better than keep restarting (as this is not Windows) but if I know it, I would never post here

Your help is much appreciated

I'm patient

Edit:
Can someone who is online on this forum more than 12hours every day to be patient for one week and not to receive one single reply? I don't think anyone could be patient more than me

Solved after formatting the HDD and install Ubuntu 10.04 again.

I have to do it manually (Enable Networking). At least, I don't have to "reboot/restart".


Thanks a lot guys for all your replies, so nice of you

Looks like I have to live with this problem forever with each and every release of Ubuntu, sigh!

Long story short. I have NEW Wireless Modem Router. I have NEW Wireless USB Adapter. I have formatted and installed Ubuntu 11.04.
Despite all that, NOW, the Wireless Connection keeps disconnecting every now and then. I have NO IDEA what's going on?

With the previous mentioned problems above, the disconnecting was somehow happening when "I" do something like "Hibernate". Now, it's happening all from itself.

Is there a solution for this problem? any advice?

I don't have money to buy a range expander so I'm using this PC as a server or somehow to connect my other PC through that one. It's a bit of a complicated story.

I appreciate if someone could help.

Thanks a lot

Sometimes, this helps:

sudo gedit /etc/pm/config.d/config

Add a single line:

SUSPEND_MODULES="your_driver"

Of cource, substitute your wireless driver. It should be listed in:

sudo lshw -C network

Here is a sample from my machine:

*-network
description: Wireless interface
product: PRO/Wireless 3945ABG [Golan] Network Connection
vendor: Intel Corporation
logical name: wlan0
version: 02
capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
configuration: broadcast=yes driver=iwl3945 driverversion=2.6.38-8-generic firmware=15.32.2.9 ip=192.168.1.111 latency=0 link=yes multicast=yes wireless=IEEE 802.11abg
resources: irq:47 memory:edf00000-edf00fff

So, in my example, I'd put iwl3945 in place.

Be sure to proofread carefully, save and close gedit.

Hi Chili555,

Thanks a lot for your reply.

There was no such file in /etc/pm/config.d so I created it and inserted this line:

SUSPEND_MODULES="rt2800usb"

I'll keep watching and will let you know in case it did not work.

[chili555]

I'm not a fan of rt2800usb. Other than Suspend, does it work well for you?

Well, I'm downstairs on another machine. I'll check it when I'll go up and will let you know.

Will "Suspend" keep the connection alive as long as possible?

Thank you again

I believe Suspend will end the connection. If the file we wrote does it's job, the driver will reload when the computer comes out of Suspend, Network Manager will wake up and the connection will be re-established immediately with no human intervention. It certainly does on my system.

I've had quite a few cases where users report it works perfectly and a few that report it does nothing. All we can do is try. No pain, no gain, etc.

That's great but just to make sure we are both on the same page, my recent problem is explained in post#4

I'll keep an eye and I really hope this will fix it once and for all.

Yes, definitely there is no harm to try

I think you know a lot about these issues.
