HP Access Point'ler ilk kurulduklarında varsayılan olarak Wireless Security Filter seçeneğini aktif tutmaktadır. Bu durumda birçok TCP-UDP portun hiç bir data geçişine izin verilmemektedir. İzin verilmediğinde de yazıcı kurulumu gibi, ping atma gibi işlemler gerçekleştirilememektedir. Aşağıda bu seçeneğin nasıl disable edileceği anlatılmıştır.
VSC menüsünden SSID ismi tıklanır.
Sol alt menüde bulunan Wireless Security Filter seçeneğinde bulunan işaret kaldırılarak Save butonu tıklanır.

New OS Installation for AOS6850
1.) Power off your OS6850
2.) When you switched it back on, stop it before the Miniboot (there is some counter counting down from 4)
3.) You will have the following prompt "=>"
4.) Enter "setenv baudrate 115200"
5.) Enter "saveenv"
6.) Enter "boot"
7.) The switch should run now in baud rate 115200 (so you have to change your clients terminal connection as well)
8.) If the speed in Miniboot is still 9600 you have to delete the "boot.params" file and reboot the switch again (the next time when the boot.params file gets created it has 115200 as baud rate in their automatically)
9.) Assuming that your connection speed is at 115200 now and you are at the "[Miniboot]->" prompt
10.) Change into the working directory with command
[Miniboot]->cd "working"
11.) Enter the following command to start your zModem session
[Miniboot]->sysStartZmodem
12.) Select all image files you want to upload (upload all .img files except Kdiag.img, Kos.img and K2otg.img - the first two are for OS6800 but you have a OS6850 and the last one is not necessary)
13.) I recommend you to upload one image file at the time as you can track better if the transfer failed
14.) Upload all the .img files as described
15.) All *.img files need to be in the working directory by now
16.) Before you reboot you have to tell the switch to run from the working directory (as it would try to load from certified as the directories are different - but in certified are no image files therefore it would fail)
[Miniboot]-> setNextRunningVersion 2
17.) Enter "reboot" to reboot your switch - it should come up with your new AOS now
Do a "copy working certified" from the CLI now to ensure that you have the images in both directories.
You only have to "fix" your serial connection speed now.
To do this enter the following from the AOS CLI:
Switch-> modify boot params
Do the necessary editing there - a help is available and I assume that you will manage it ... Now you need to reboot the switch and change the same in the u-boot back to 9600 (just follow step 4 and 5 in the u-boot again)
2.) When you switched it back on, stop it before the Miniboot (there is some counter counting down from 4)
3.) You will have the following prompt "=>"
