Re: RPi not booting after Update

Thank you WallaceIT! That was it. I followed your instructions (did not have to chmod anything btw) and now my RPi lights and flashes in all colors again :)

Re: RPi not booting after Update

Thank you Rattus for your information and thank you malakai for your detailed information ;) I downloaded the RPi Firmware from Github and compared md5sums to the files in my boot partition. There were no differences, all values were the same. Reinserted the SD card in my RPi and still green LED is ...

RPi not booting after Update

I made a script to update and - if necessary - reboot my RPi automatically. This script invokes apt-get update, apt-get upgrade and rpi-update (by hexxeh). It worked several times and rpi-update was run several times succesfully also. My log files report everything went fine and a reboot is needed. ...

Re: WLAN too slow

That was not the problem. I used rpi-update and my stick is still stuck at 802.11bg in iwconfig when it is 802.11n in lsusb :evil:

Re: WLAN too slow

Does anyone else have an idea about whether to install one of these drivers and how?

Re: WLAN too slow

Good point from stupid_boy ;) How comes iwconfig shows 802.11bg when lsusb shows a 802.11bgn chip? I would think it might be the driver but it seems that all those 8192cu.ko scripts were about half a year ago, now as the end of your link states it should be fixed and I am at the latest version: [email protected]...

Re: WLAN too slow

"2 m away from the AP and has a direct line of sight"? are you kidding? and may be your AP is at HIGH power? try from bigger distance and/or lower AP power. most likely you are overloading radio circuity. WiFi standard set maximum allowed signal at -28db ( or similar ), from what i see till now, th...

Re: WLAN too slow

Hi jamesh,

as you can see before I had a link quality of 100% but I gave it a try. My RPi is now 2 m away from the AP and has a direct line of sight. Unfortunately that had no improvements, still about 900 kB/s transfer rate :(

Re: WLAN too slow

No I had it directly connected. But does this make any difference? If the RPi doesn't get enough power, it would crash/freeze/restart and it would not reduce the WLAN speed or am I wrong in that point?

Re: WLAN too slow

@obcd: The stick is directly connected. Yes connection speed is at G speed, but I don't know why it doesn't connect at 150 Mbit/s. By the way I just found this: [email protected] ~ $ iwlist wlan0 bitrate wlan0 4 available bit-rates : 1 Mb/s 2 Mb/s 5.5 Mb/s 11 Mb/s Current Bit Rate:54 Mb/s My RPi doesn'...

WLAN too slow

Hi everyone, I'm a proud Raspberry Pi owner but I have one problem: I use my RPi (amongst others) as an FTP server. When I upload files using WLAN, I get around 900 kB/s. As this is not enough in my 802.11n network, I tested the SD card using hdparm -tT /dev/root and dd if=/dev/zero of=testfile and ...
