Cisco Ap console connection issue through Usb-serial converter

Esteban Talavera — Sun, 04 Jul 2021 05:46:40 GMT

I'am trying to connect to AP-1042N console port using a Usb serial converter.

I can connect to one cisco 2950 switch with the same usb serial converter.

I can connect the AP directly to a desktop serial port without the serial usb converter

The usb-serial converter works fine qith routers switches, but the ciso AP.

Is there a known issue with the AP console port with the usb-serial converter?

Thanks

I use a USB-serial all the time and it works like a champ. One thing to check, make sure flow control is set to off.

Sounds like the console settings on the ap may have been changed .. Did you reset the ap back to factory ?

The settings in your terminal program need to be 9600/none/8/1 and flow controll off/none.

HTH,

Cisco Ap console connection issue through Usb-serial converter

neeraj_563 — Tue, 12 Feb 2013 08:13:51 GMT

Hi,

I have the same USB to serial convertor cable as I dont have a serial port on my laptop. Using this I am not able to console Cisco access points. I have tried on Cisco Aironet 1100 & 1200 series Access points yet.

But with the same cable, I am able to console into Cisco Switches and routers.

Keeping settings like Stephen Rodriguez suggested above also does not work.

If I use the console cable through my PC which has an inbuilt serial port, it works like a charm with same settings. I replaced the USB-Serial adapter but still the problem remains the same. Baffo Adapter image attached.

I will appreciate if someone has figured out the solution. The problem still persists.

I have never used that. This is what I have used forever and I have had no issues at all. I have used this on windows and macs.

Hi Esteban, Did you get a fix to this problem ? It seems even 4 years later this issue still persists.

I am using a usb to serial converter but its not working with the AP, but works great with other switches and routers.

Let me know if you got a workaround or a fix to this issue.

Make sure flow control is disabled. This is a setting that is different from routers and switches.

That didnt work. I have tried all possible combinations with Flow control, "None", "Xon,/Xoff", "Hardware". Even tried to change the software from tera term to Putty. Its just not working.

You need to find another cable. There have been other post in the past with the same issue you have and they ended up using a different USB cable.

I have recently used this along with their Air-Console and iPad/iPhone RedPark cable. The cable seems to be very stable with certain windows machines that tend to blue screen with various prolific drivers. I run this cable also on a MacBook.

I seem to be having the same cable issues the other posts mentioned. Is it something to do with the cable being non-prolific, vs prolific?

Hello,

I had this problem. I could connect to routers and switches but with the same cable it was impossible to connect to an access point. I use Linux/Ubuntu and minicom software.

I decided to try with a different software. I chose putty and it worked on the first attempt.

Maybe you should try with a different software.

The settings for the switch

Scott Fella — Sun, 30 Mar 2014 14:33:17 GMT

The settings for the switch/routers can be a bit different... with wireless, most of the time its due to flow control being set to something other than None. Why is this or why does wireless equipment have more trouble.... who knows. I have just stuck with SecureCRT, also use Putty and MobaXterm. The cable I use is Get-Console and also use their Air Console.

Scott Fella — Fri, 04 Dec 2015 13:30:30 GMT

You need to try a different Ian to serial and also a different device. If you search the forum, you will see that many have had issues and some was fixed with getting a different use to serial device. Even if the sub to serial works on other devices doesn't mean it will work on an AP. Yeah that is weird to say, but it's true:)

brad — Tue, 02 May 2017 02:42:21 GMT

Having the same problem - as per the advice here I've now tried three different kinds of USB-serial cables with no result. Can connect to routers and switches just fine.

I'm using SecureCRT, but also tried Putty - no result.

Very, very annoying.
