Wireless networking degraded with Fedora 18

0 votes
325 views

I have an HP laptop with an integrated Broadcom controller:

 02:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

I recently upgraded to Fedora 18, and have noticed a big difference between wireless networking performance. With Fedora 18 running, and sitting about 10 feet from a Linksys WAP54G access point I get "one bar" on the Gnome icon... if I double the distance, I start losing the connection.

If I reboot to Fedora 17, I get three/four bars at 10feet, etc.

I've checked the internal antenna cables, and made sure that each OS is running the most up to date kernels. I even used a spectrum analyzer to look for noise in the 2.4GHz spectrum. I don't have any external USB WiFi adapters to test with.

Regardless of the number of bars, is the download speed similar or very different under the two versions? (I ask because there was some talk earlier about the number of bars becoming a more accurate assessment --
I don't know if this has been implemented).

Try this (or related sites) to get a reading: https://speakeasy.net/speedtest/

Note that there is, quite naturally, tremendous variability, so you may have to do it a large number of times to get a fair reading under each distribution.

If all was well with the equipment, I'd expect a much better indication than just one bar at a meagre distance of 10 feet, it doesn't sound like a more accurate reading. It's hard to imagine a transmission/reception
problem with that small distance.

We are developing internal software using MySql dB and are planning to use Fedora for the server.

The question is how do we know that this hardware (motherboard, CPU) really support Fedora version 18 or 19? We are looking at mobo from Asus or Intel or Gigabyte, but did not find firm answer. We did not find the info from mobo websites either.

The mobo that got our interest are the ones with H77 or Z77 or H87 chipsets.

Is there any URL for me to get the information we need?

The Sound Icon came up missing from System Tray after reboot, It is not even in Hidden Icons.
How do I get The Sound Icon back in System Tray ? If I click on Kmix from Menu it won't start and display Kmix. If I remember it was just after I did a Update.

Is there a simple way of changing the font used by lpr to print out a text file,
after say "lpr foo.txt" on a Fedora-18 CUPS printer?

The font in my case is much too small for my eyesight.

I am on the verge of a rather thorough hardware upgrade, ie. motherboard/cpu, and in addition want to migrate from XP 32 to Fedora 18 64. So, now it occurs to me that all the drivers from Windoze will be
gone--are there drivers in the Fedora CD package, or will I have to hunt them down? Actually, there may be a more basic driver issue--namely, running the CD player itself: the driver won't be loaded yet. Is this a
problem? I also have an ISO image on USB, if needed.
