If the keyboard is like most 2.4GHz wireless phones it uses FHSS instead of DHSS like your typical home wireless access point. Basically with FHSS you have 15 non-overlapping channels opposed to 3 for DHSS. Wireless phones use FHSS because it has better frequency rejection capabilities. DHSS provides better throughput with less interference rejection so you can probably guess why WAPs use DHSS. If you run your 802.11g on channel 11 you might be able to get away with it but I won't guarantee anything. If there is an option for a 5.8GHz wireless keyboard I would opt for that or one of the older 900MHz models.

[gentoo-user] Abysmally slow 2D performance using proprietary Nvidia driver on dual Xeon system (EMT64)
Greetings, I have been trying to fix a somewhat puzzling and annoying problem over the last couple of months that has me absolutely stumped. I have been unable to isolate the cause of the problem and it appears to be intermittant at best. The issue rears its ugly head as follows: This is on a dual boot workstation with a Supermicro X6DAL-XTG motherboard, dual 3.0GHz Xeon processors and a GeForce 6600GT video card. The system has worked splendidly since I purchased it back in June with one exception: occasionally when rebooting the system to return to Linux from Windows the 2D performance in Gnome is terrible. The problem does not appear immediately nor does it happen every time. Initially gdmgreeter appears as it should and I enter my login credentials. The Gnome desktop loads quickly and as I start to work applications load normally. However, after about 10 minutes the system load on one processor sharply increases to 100% when performing a simple task such as clicking on a button in Firefox, launching a new gnome-terminal window or clicking on the Applications menu at the top of the screen. The response time between clicking and the menu appearing for instance is anywhere from 2-5 seconds. There does not seem to be any quick fix for this which is what has me puzzled. If I close all of my applications, log out and log back in the problem resets. Rebooting the system proves ineffective as well. I have tried various driver revisions, currently using 1.0.6629-r4, and several different kernels to no avail. I have tried both enabling and disabling the RenderAccel option in /etc/X11/xorg.conf and that does not appear to make any difference. Adjusting the NvAGP option does nothing nor does enabling the Composite option however the system seems more responsive when the Composite option is enabled. Switching to the nv driver resolves the problem and the system remains snappy with no immediate problems. Occasionally I will begin to get artifacts on the display with the nv driver and then the screen goes entirely white but switching to the console using ctrl + alt + F1 usually resolves this problem. I would appreciate any insight anyone could provide as to what I am overlooking. I have walked through the Gentoo Nvidia documentation numerous times and I have consulted the README document included with the nvidia driver. I am completely stumped. Currently I am using 2.6.9-gentoo-r9 for a kernel with the 1.0.6629-r4 version of the nvidia driver. As I said before I have tried several kernel and driver revisions to no avail. As a sidebar, 3D performance seems to be as it should be which puzzles me further. Again, I appreciate any advice anyone may offer. Please see the following links for the last xorg.conf I tried as well as my kernel config and make.conf http://pizon.org/xorg.conf http://pizon.org/kernel-config http://pizon.org/make.conf

Re: [gentoo-user] Recommend me a good PCMCIA wireless network card
Just remember, if the laptop isn't going too far, a good length of Ye Olde Cat5e is a much cheaper solution. That being said... Changes the possible security implications too... Yeah, I picked up a great Orinoco (branded as Enterasys) at Rokland.com last month for roughly $50. Atheros chipset, 802.11a/ SuperA/b/b+/g/SuperG... very nice. It works in Windows (with the driver CD), Mac OS X (with the shareware OrangeWare driver--totally worth the $15 shareware fee) and, naturally, Linux (with MADWIFI). It picks up Channels 1 through 14, and can put out up to 100 mW of power (40 mW on A networks). I forgot about Enterasys and Atheros. The Orinoco-based cards have power output of around 24mW and the sensitivity is right around -83dB which I've found works well in most situations. I usually see about 3.5mbps of throughput when connected at 11mbps. Could be better but it gets the job done. Btw, I think YDI (Terabeam) still sells an Orinoco-based card. They've got really good support should you need it. There's no antenna jack, though, but I hear most PCMCIA Orinocoes can be modded to include some kind of external jack; I'm not that desperate for power, but with dial-up at home, I might do that mod and build a yagi antenna, get in my car, and... well, you get the idea. :-) I've got three or four of the cards back from the days when they were still made by Lucent and with the proper pigtail you can connect an external antenna. In fact I used to use Orinoco PC cards with a PCI adapter to deliver high-speed access to folks around here and they worked quite well, then the telco showed up with DSL but that's another story. As for the newer cards, I believe the Proxim cards can be modded by opening the antenna housing on the card to get to the antenna connector. If you want to go to an external antenna check with YDI, I think they still make PC cards with external antenna connectors. Still haven't had any luck with KisMAC (the OS X port of Kismet), though. It finds my card but doesn't detect my wireless network... I'll figure it out eventually. Maybe the drivers don't support monitor mode?
