Fedora 14, slow wireless

I’ve recently posted a link related to Slow network under Fedora 14 distribution. The solution provided is related to iptables and is still working (on my distribution at least). However, I’ve also noticed that the wireless remains very slow while a wire connection works well. Many Fedora users seem to have the same issue.

It has been quite difficult but I finally figured out a solution to get back a fast (normal) wireless connection. The main idea is to play with the mode, as suggested on some forums. I won’t explain what is the mode. You can figure out what is the mode y typing the iwconfig in a shell. Information is printed on the screen. It looks like:

wlan0 IEEE 802.11bg ESSID:"*******"
Mode:Managed Frequency:2.452 GHz Access Point: 00:1E:37:11:5B:63
Bit Rate=54 Mb/s Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:on
Link Quality=68/70 Signal level=-42 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

the first line mention the mode: 802.11bg. In this case the mode is bg. Some people suggested that the mode of your internet box must be changed to b-mode only. So, I connected myself to the Livebox by typing

in Firefox. A menu appears requesting a login/password. Then, you can go to the wireless submenu. There, an option allows to switch the mode from bg to b only.

It did not seem to solve the issue but I kept this configuration.

Then, I went to the Fedora System menu ->preferences->network connections. There, I select the wireless tab, which options can be edited. Now you have a mode option (set to infrastructure by default). I set it to adhoc. Save and restart the network. Restart Firefox and it works for me !

Now, the question is “was the provider box step required ? “. I should get it back to mode bg to see if the first step was required.

Another issue: although the wireless is now much faster, there is always a short delay of about 1-2 seconds before the page opens. I think this is a DNS issue, another issue to be solved…
