Problem With AIR-AP2802I-C-K9

Level 1

Hi,

I am facing problem with AIR-AP2802I-C-K9 that the client get very low speed. We are using WLC 2504 with 8.3 OS version. We use country code US and PK. We also use AIR-CAP1702I-D-K9 and this has no issue. I also check the country code for  AIR-AP2802I-C-K9 but we did not get the country code for -C region.

Please advise us the solution.

Thanking you-

Azizur Rahman

Is your client using Windows 10 creators update (build 1703)? If yes, there is a known issue in Windows, which is fixed in the Windows 10 build 15063.447.

This is KB4022716.

If you run any other version of Windows, you might need an updated driver for the Wi-Fi card. If it's an Intel 802.11ac card, get at least Intel Wireless Driver Pack 19.60.

Thanks for your reply.

When my PC is connected with 1702I AP, then I got 12MBps but when my PC is connected with 2802I AP, then I got max 5 MBps. 

Here I would like to mention you that we are using 2960x-24PDL to connect the APs.

Please advise.

Thanking You-

Azizur Rahman

Just to be sure, 12 MegaBytes per second, right?

12 MB/s is still a bit on the low side with the 1702i, but much better than the 5 MB/s.

When you're connected tot he 2802i, what connection speed does your client show?  It should be something like 54, 144, 173, 300, 450, 600, 866 Mbps.

Dear Patoberil,

When PC is connected to the 2802i, the client shows 5MB Max.

Thanking You-

Azizur Rahman

And what wireless connection speed is it showing?

Here a manual for Windows 10: http://winaero.com/blog/see-the-ethernet-or-wifi-adapter-speed-in-windows-10/

Dear Patoberli,

It is 144 Mbps.

Thanking You-

Azizur Rahman

That means you are probably running a 20 MHz channel on the 5 GHz or you're connected to the 2.4 GHz band.

Do you have AP Groups configured?

Can you check the configuration of the AP and the check what channel configuration is set?

Also make sure, if you use DFS, to have the country selected and all allowed channels.

Old thread revived? Was this ever resolved as I have the same issue. Pulling my hair out at this one.

 

Have old 3602i on desk within 1m

Have new 2802i on desk within 1m

Both AP configured with Do0 2.4 20mhz and Do1 5ghz 40mhz/80mhz

Both AP connected to same switch with same configuration. Even tried swapping ports to isolate but symptoms followed.

 

5ghz works fine as expected on both AP

Connecting pc and mobile to 3602i 2.4ghz and connect rate around 200mbit on both devices as expected.

Connecting pc and mobile to 2802i 2.4ghz and connect rate is 5mbit on both devices. However, initial connection shows 130mbit before dropping to 5mbit. Traffic throughput confirms ~5mbit download and >1mbit up.

 

Both AP Do0 2.4ghz radios show same configuration for data rates 1-54, m0-23 etc.

 

The 2802i is running Mobility Express 8.8.100.0, but older firmware has been tried but symptoms remain.

Clearly this is an issue with the 2802i firmware or configuration, but is there a way to resolve this?
