hi every one, right now  i have problem with a bridge 1310g  i can't console it at all

i did already use the setting  below and i have tried all the baud speed rates and no response at all

Is also nothing appearing if you reboot the AP while it's connected to the serial port?
You might also want to try Putty or another serial client. Also make sure to have the same options in your serial client.

If you still don't get any characters on screen, it's possible that you must switch the RX and TX pin on the cable.

did also do restart the ap after i have opened  the session  and no luck

how to  change RX and TX pin ???

This is a customers help customers forum. I typically don't answer on weekends.

Regarding your problem, please see here for some theory about serial cables: https://www.cisco.com/c/en/us/td/docs/wireless/access_point/1240/installation/guide/1240hig5/124h_e.pdf

Do you use an original Cisco cable or a third party one?

Do you use an USB-Serial adapter or has your PC a built-in serial port?

[AbdelrahmanShoukry4468]

no i don't have original cable

i use this one

and did use this converter too with normal RJ45 cable

without any result but i did use both of them on another device and worked perfectly 

i have serial port on my PC

Hmm, ok the blue cable should work (if it's the Cisco one, there sadly is no real standard in regards to serial ports...). I suggest to try another PC, or an USB-Serial adapter for testing.

There is a possibility that somebody changed the speed of the serial port on the AP (you can do that in ROMMON). In that case you have to try all the different speeds until it doesn't show any garbled characters. 

Or it's possible (but very rare) that the serial port is broken on the AP.

[edit]

Just realized that this AP doesn't have a "normal" serial port.

You do have the converter, like outlined here? https://www.cisco.com/c/en/us/td/docs/wireless/access_point/1300/installation/guide/1300hig6/130h_c4.html

Maybe that converter is broken. 

[AbdelrahmanShoukry4468]

I don't understand what do you mean by normal serial port
And as i mentioned before i have already tried every speed on the hyperterm and putty with no luck at all
And i already tested the cable and the converter on another device and worked perfectly 😢
I running out of options here 😭😭

Was the other device also an 1310g AP? If yes, then the AP is maybe broken.

[AbdelrahmanShoukry4468]

No it wasn't.
But no other suggestions??
