I'm experiencing some rather erratic Wifi behaviour with my laptop. Since there are so many factors involved, I have trouble pinpointing the problem.
My setup is as follows: A Lenovo x121e with Arch installed, and a Realtek RTL8188CE card; a Hitron CVE-30360 cable-modem and a DLink DI-524 router. I've used this How-To from DLink (beware: German Dlink HowTo) to setup the DI-524; in essence: deactivate UPnP, changed IP to 192.168.0.222, turned off DHCP-Server, connect cable modem to LAN port of the DI-524. My desktop, which is connected via cable to the router, connects to the internet just fine.
With my laptop, I want to use the Wifi, obviously. I set the router to use WPA (also tried WPA2, no difference), and then connected with either wifi-menu or wicd-curses. It establishes a connection, yet it is very slow most of the time, and drops packages (up to 10% package loss when pinging the router).
What log files etc. would I look for, I don't really know where to start with this.
Thanks in advance

Search these forums for the kernel module your card uses. You apparently have the Thinkpad b/g/n wifi card, which uses the rtl8192ce module. This is unfortunately one of the poorest functioning "supported" wireless card in Linux that I know of.
Do that search and you should find some things that might help, but there really is no other solution than changing your wireless card.
Download the firmware for a DI-624 and "upgrade" the router with it. Make sure you are upgrading over an ethernet link and not a wireless connection.

I may have to CONSOLE you about your usage of ridiculously easy graphical interfaces...
Look ma, no mouse.
Just tried a Linux Mint 14 Live CD, and although not completely stable, it is a lot better, even bearable I'd say. Any idea what would be different?
Had the same problem here. The source of the probelm is the crappy module rtl8192ce!
I solved the problem by using a intel wireless card now. I bought the intel N6200 and everything is fine now.
But be careful: You have to mount the card in the free pci slot (with a adapter), if you replace the original wifi-card the BIOS will complain and you have to flash a differnt BIOS where the intel card isn't blacklisted.
