[gentoo-user] Wireless connection.
Hi, I installed a netgear 802.11g card on my laptop for wireless access. With latest vanilla-source (~x86) everything was working fine. Then, I changed the kernel to latest gentoo-sources (~x86). Now the wireless connection doesn't connect automatically after boot. I have added it to the default runlevel. Now everytime, I have to start it explcitly by: /etc/init.d/net.eth1 stop /etc/init.d/net.eth1 start I have to stop first, cause it say it is already started. What could be the problem. I will appreciate any help. Thanks Prabhat -- [EMAIL PROTECTED] mailing list

If this were a Prism-based card using the linux-wlan-ng ebuild, I'd say that you need to be sure to start up the wireless LAN (/etc/init.d/wlan) before you start up the network device. This could be accomplished by adding a dependency in /etc/init.d/net.eth1. Since you're not using that particular software... the best I can do is an educated guess: you might have a similar dependency for that software. That is, there might be some other system that has to start up first for eth1 to come up properly. Nathan Meyers [EMAIL PROTECTED] -- [EMAIL PROTECTED] mailing list

Try doing this: Take the 50Ohm terminator out of your rg-58 (assuming you're not using utp) and see what happens next. Say...cant browse the web at those amazing speeds of 1.1Mbyte/s,uh?:) Its called reflection. In a wireless RF connection you have: -Refraction -Reflection -Interferences (usualy dont affect 10base2 due to cable shielding) -Attenuation due to property of the medium (air) In wlan if one client says ACK and the other receives ACKCC## he will ask :could you please repeat that? This is why you dont achieve such speeds with wireless rf connection.Good antennas (or well designed internal antennas),low SWR,etc will improve speed and distance. This is why some wlan hardware is more expensive than others Apart from that keeping objects away from the antenna (at least) 1 wavelength can also improve Tx/Rx.1 wl for 2.4Ghz is ~ 0.125 meters I don't know if this would help but trying definitely won't hurt :) Anyway take on account that the two machines are side-by-side so no interferences should happen.
