I recently ugpraded my router's (buffalo wzr-hp-g300nh) firmware from dd-wrt to open-wrt due to problems with installing packages to dd-wrt's lates version. Looks like open-wrt now is more up to date and works better.However it is easier to break. After playing with it's GUI to configure network I easly bricked the router and needed to recover it. What I found is failsafe mode in open wrt.To achieve this with buffola wzr-hp-g300nh, simply unplug the rooter wait for red diagnostic light to turn of , when the green light starts blinking immediately press the wireless button. This will put the open-wrt in fail safe mode.To be able to access failsafe mode , you should be connected to your router over cable and your ip address should be set to 192.168.1.2 (static). Once you are in , just telnet to 192.168.1.1 and you will be logged in. first mount the file system so that you can write it by typing: mount_root when you do this , FS will be writable. I found def...

I recently moved to a new flat and currently I don't have an internet connection.I have an old phone: nokia n95 8gb and unlimited data plan. What I decided to connect the phone to the router and access internet as usual. 1-install open-wrt's latest version (OpenWrt Backfire 10.03.1-rc5 in my case) 2-you need to install usb packages kmod-usb-acm 2.6.32.27-1 kmod-usb-core 2.6.32.27-1 kmod-usb-ohci 2.6.32.27-1 kmod-usb2 3-to configure 3g access from backfire's gui you need install package comgt 0.32-9 4-go to wwan section and now select 3g as connection method. put the settings apn etc. and you will be connected to internet over your nokia. Trick here for nokia phones is comminicated through kmod-usb-acm package ...

I have a Buffalo WZR-HP-G300NH modem and I run DD-WRT v24-sp2 (08/07/10) std on it. everything is perfect except I need to have my old router's mac address to keep my old IP address assigned from my ISP. There is a solution in DD-WRT for this in WEB interface > SETUP > MAC address clone where I can change it and it fixes it . However the problem is for some reason or because of a bug, Buffalo forgets MAC address every time it is rebooted or at a power lost and I need to go this address and click apply again to change it back to the desired MAC address. My solution to avoid this is easy: 1) Go to Web interface > Administration> Commands 2) Paste this: nvram set wan_hwaddr="12:40:CC:11:00:00" stopservice wan startservice wan Not that: "12:40:CC:11:00:00" is my MAc address and you need to type your own there! 3) Click Save Startup Next time when you reboot your Modem , or after a power lost you will have the desired mac address set.

9 years ago I recorded half of a song hoping that one day sound recognition technology will advance and I can find out what was the song's name and listen it as a whole.Today by coincidence I found that file again and used shazam on iphone to identify which song was it.maybe I am a bit late but now at least I know that it's called first cool hive and I can stream it from spotify.

I had some problems for a while with my laptop about things getting slowing down while I was using my pc.Normally, slow downs occur if the CPU usage is very high and normally I use Task Manager to see what's going on.The interesting thing is when I open the task manager I see some processes using high CPU and I kill them , suddenly another process starts using CPU higher..after a while killing all the processes I end up with Task Manager and task manager uses massive CPU, obviously these processes were not using this much CPU. The first thing came to my mind is a driver problem.But how could I find it and prove which driver was it ? Normally you can do debugging and all kind of stuff to track down the problem but it's a massive work. I was searching the net I found this utility: http://www.thesycon.de/eng/latency_check.shtml great tool, showed me the lag and intervals so that while I was running this program I went to device manager to disable drivers one by one to see whic...

today I had to restart my jailbroken iphone because it was getting slow.I was surprised when it didn't boot and stuck while loading the OS.I was lucky that I was using verbose boot thing so that i was able to see what was going on.my problem was related to some fsck error during the boot. I tried hard to capture what was the error message because it was restarting quickly after that step.I used to use linux system and thought that the problem was with a corrupted unix filesystem however it wasn't.After doing some googling i found that thousands of people had this problem and looks like thousands of will have.Some clever guy had found that the problem was because of an update to /sbin directory from the jailbreak community (cydia/rock etc.) . and used one of the jail break programs with some customization to restore the sbin directory. That way you don't need to restore and start everything from square one.Also you won't loose any data. The blog of this guy and the more ...
