Tom's questions

After a fresh install of Ubuntu 13.04 64-bit, my wifi is now misbehaving. It seems to lose Internet connectivity from time to time, so this results in, for example, the web browser stops loading sites at the middle of the process, wait ~3 seconds, and then receive the rest of the site. This didn't happen in 12.10, in the same laptop.

Another symptom that anounced that something was not going to be alright, was the wifi disconnecting for a moment when I hit "Continue" in the first stage of the Ubuntu installer, in the screen where you select "Update during install" and "install MP3 support".

I have a Broadcom BCM4313 card (actually it's a "Dell WLAN 1501" card, but at this moment I don't understand very well how this two brands relate to each other)

~$ lspci -vvnn | grep 14e4
12:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)

I've read that this might be a bug in the current driver shipped in Ubuntu 13.04: bcmwl-kernel-source 6.20.155.1+bdcom-0ubuntu6

How do I downgrade to a previous working version?

I tried following this instructions but 1) I can't install the old version from the repository because it doesn't seem to be available for Ubuntu 13.04. and 2) If I manually download and install a .deb file from here (bcmwl-kernel-source_5.100.82.112+bdcom-0ubuntu3_amd64.deb) , after reboot the system drops the wl controller and selects again the brcmsmac controller, as shown in the "connection information" dialog screen from the notification area. Then, if I try to select it manually, I get:

~$ sudo modprobe wl
FATAL: module wl not found.

Does this have something to do with the kernel version? i.e. the .deb package not being compatible with my current kernel. Any ideas? Maybe I have to recompile that source package? If so, how?

Thank you.

I've been using ndiswrapper to make work some wireless cards using its Windows drivers, because they are not yet supported by free Linux drivers. Until Ubuntu 12.04.

Now, I can install Windows Wireless Network Drivers (ndisgtk) from Ubuntu Software Center but when I try to load the driver, I get an error message saying

FATAL: Module ndiswrapper not found.

I get the same error if I type on a terminal sudo modprobe ndiswrapper.

How can I workaround this bug until it's fixed?

The two-channel auto-type obfuscation feature of KeePass doesn't work for me with Chromium (on Ubuntu 12.04 64 bits). However, it works just fine with Firefox.

Dows anyone know how to fix this?

Textboxes in web forms in Chromium seems to have something special that causes this feature to fail. Only some of the username/password characters are being auto-typed.

This might be related to this: if I select an entry in KeePass and click "Copy User Name", I can paste it fine with Ctrl+V in any textbox in Firefox, but I can't on Chromium. However, text copied using Ctrl+C from a regular text file (say, from gedit), can be pasted fine on both browsers.

What may be wrong?

I wouldn't like to deactive this feature for all the entries in my keepass files as I use them on Windows too and they work just fine there (even on Google Chrome for Windows). This feature gives an appreciated extra security measure against spyware/keyloggers.
