ESSID gets truncated

This does not seem to be an issue in the latest wireless tools. What version exactly are you running?

The current version is: 28-1ubuntu3

Thanks for taking the time to report this bug and helping to make Ubuntu better. We have not heard from you in a while and we wondering if this is still an issue for you. If it is what wireless card do you have? You could post 'lspci -vv' to the bug report. Additionally what driver does that device use? The result of 'lsmod' would tell us. Thanks in advance.

It's a PCMCIA card that uses the driver r818x. I still have to use an script that configures the ESSID with a letter more, wich gets truncated.

I'm not on my PC now, I can not give more info. I'll do at home :-)

This is exactly the same for me. I enter the essid in the network manager but when I iwconfig it is truncated. I pad with an extra character and all works OK.

I have a belkin f5d6020 v3 pcmcia card that uses the rtl8180 driver.

I am using the latest beta of Feisty as at 13 April through a distribution upgrade on Xubuntu

That happened to my also. The only way to connect my wireless was to create a script that runs on start up when I define the essid with one extra character as in iwconfig essid whomeZ key <key>.

I have this exact same issue using a Linksys wpc11 ver .4 (r818x module). Worked fine on 6.10 but after clean install of 7.04 my ESSID was being truncated by one character as described. I am not using gui tools to configure my wireless adapter I am directly editing /etc/network/interfaces. My wireless-tool is at version 28-1ubuntu3.

I've got a similar issue. After trying to "connect to another wireless network" and entering my SSID (XBOXWAP) I open a command prompt and run iwconfig only to see the essid="X"

So only the leading character in my ESSID is retained and all subsequent characters truncated.

Tried it with my neighbor's "linksys" and iwconfig reported just the "l"

Also, this only happens intermitently. Sometimes I reboot and it is working like a champ again with no problems. Other times I don't see any wireless connections whatsoever.

What is the workaround for truncating all but the first letter in the ESSID?

Let me know if I can provide any further information towards resolving this bug.

Thanks,
JJJ

One more thing. Sometimes Keyring Manager prompts me for its password (and I typically get on the network). Other times it does not prompt me at all.

Could this be Keyring Manager's problem.

I confirm the problem. I simply add a character to my essid and I get connected. Module r818x with device "02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8180L 802.11b MAC (rev 20)"

I'm having the same problem -- last character of my ESSID is being dropped with 2.6.20-16. Using linux-image-2.6.20-16-386 and wireless-tools-28-1ubuntu3; all packages current as of today for Feisty Fawn / 7.04.

If I boot into an older kernel (linux-image-2.6.17-11-386 (same system, not changing any other packages), this problem goes away. (Unless I've implemented the extra-character workaround in /etc/network/interfaces, in which case the problem comes back, but anyway....)

Interestingly, just after the upgrade to Feisty Fawn, the r818x (and the ieee80211-rtl it depends on) module no longer loads automatically. A simple "modprobe r818x" fixes this, but shouldn't be necessary. No evidence yet this is related to the ESSID truncation.

Never mind on my automatic load complaint -- seems others have had problems in the past:

Excerpt from my /etc/modprobe.d/blacklist:
# buggy driver causes kernel BUG on load (Ubuntu: #78255, #88430)
blacklist r818x
blacklist r8187

(module-init-tools-3.3-pre3-1ubuntu7)

Similar problem running Feisty Fawn. Retrying with various length names gets different results on different attempts.

This patch solves the problem of r818x cards.

I am running Edgy Eft with KDE 3.5.5 and have tried several times to upgrade to Feisty, but my wireless never works, and I end up going back to Edgy. I have a Linksys wpc11 ver.4 with the 8180 chip, and can't seem to get the card to show the second led. I am fairly new to Linux, but even tried with ndiswrapper according to instructions online. Still couldn't get the card to activate, let alone connect to anything. how would one go abut using the above patch?

Liu Qishuai, how we can install this patch?

Is the patch supplied above going to appear in feisty backports soon, or do we need to upgrade to gutsy?

I am told a workaround that may work is enclosing the essid in quotes. Can anyone confirm this ? Otherwise the only way to get this update is upgrading to Gutsy.
