Roaming issues

Emerson Rodrigues — Mon, 05 Jul 2021 07:24:06 GMT

Hi,

I'm having roaming problems at a customer.

I have 1 WLC 5508, software version 7.4.110.0 and 20 AP (AIR-CAP1602I-T-K9) installed on the head office and 15 AP x 3 Branch office.

The roaming problem occurs at all sites, even using 2.4 or 5 ghz and with any devices, laptop, mobile, tablets.

Sometimes the connection drops, other times I need to disconnect and connect again to the WLAN.

Sometimes I have poor signal, even if I move bellow another AP, the roaming doesn't occur.

Troubleshootings that I did:

Site survey using Airmagnet Pro, there is some others SSID on same channels (2.4 GHz, 5 GHz)
Debug tracking an user mac address, but nothing was found.
DCA channels config to default, DCA channel list remains 1,6,11.

Additional information: This issue also occurs using 802.1x or WPA PSK.

Should I use static channels?

Any advice is welcome.

Thanks.

You need to make sure your

You need to make sure your using WPA/TKIP of WPA2/AES, not a mix of either or both at the same time. Try that first as you have no issues with other authentication methods, so no need to change anything else.

Hi Scott, thank you for

Hi Scott, thank you for answer.

I've just tested with WPA2/AES and the issue is still happening.

I tried without authentication and still occur.

At this moment I have 525 Rogue APs listed on WLC... May I disable A/B/G/N low data rates, is this a possible issue?

Thanks

in the debug output i can't see any reassociation request from the client ,

if this debug collected while the client is roaming between two APs , then the issue is either a coverage hole or a client side issue ,

please share traplog

Thanks for helping

Thanks for helping I've disabled the data rates under 11mb from both 2.4 and 5 GHz. The roaming issue is no longer happening.
