Poor data rate at client reception level

alikhelalfa — Wed, 25 Sep 2024 10:01:23 GMT

Dear team,

I'm facing some connectivity issue with some client, random disconnection that impact the productione line, 802.1x is used for corporate netwrok .

i run a script on windows level that check the signal strenght ,i will share with you some result

the signal power is goog 83% but the reception debit is too poor (about 6mbps)

Type de r�seau �: Infrastructure

Type de radio �: 802.11ax

Authentification �: WPA2�-�Entreprise

Chiffrement �: CCMP

Mode de connexion �: Connexion automatique

Canal �: 36

R�ception (Mbits/s) �: 6

Transmission (Mbits/s) �: 287

Signal �: 83%

i found some articles for troubleshooting,

any advice what the real issue and if add this recommendation what is the impact behind it ?

Thanks in advance

Hello @alikhelalfa,

Just to be sure, which product are you asking about? WiNG Distributed, XIQ Pilot or XIQ-Controller? What are the ap models and what firmware version are they on?

Hello

The product : XIQ Pilot

APs models: AP410C

AP version : 10.6.2.0

Many variables may affect the environment so we need to start with the most basic:

1 - Is this a new deployment?

2 - Was it working at any point?

3 - If it was working, what changed?

4 - Are you using the default AP template and radio profiles?

5 - How many APs in the immediate vacinity of problem area?

6 - What type of environment: Office, warehouse, etc?

7 - Is it impacting all wireless clients on all SSIDs?

If this is impacting production, you may want to open a GTAC ticket versus going through the hub. Just a suggestion.

Hello Christoph,

1 - Is this a new deploymen to? No An existing infrastructure

2 - Was it working at any point? Yes working in general except some of them with a lot obstacles for industrial envirement

3 - If it was working, what changed? nothing was changed , the first time ware only some AP and now we add new for better coverage

4 - Are you using the default AP template and radio profiles? Yes

5 - How many APs in the immediate vacinity of problem area? On this building there 7 ,

6 - What type of environment: Office, warehouse, etc? wherehouse and industrial envirement that need constant connectivity

7 - Is it impacting all wireless clients on all SSIDs? Presisely on the wifi Corporation with 802.1X authentication, personal WPA2/WPA3 is good

If this is impacting production, you may want to open a GTAC ticket versus going through the hub. Just a suggestion.

For opening the ticket a did before but i did't get reel analysis for this like you do now, thanks for help

Hello @alikhelalfa,

This needs more indepth analysis which can't be done on the hub; however, by looking at your answers I can deduce that you may have an environmental issue. The APs are using the default template and profile which is not recommended since the radios are blasting at 20db power (so EIRP is much higher) DFS channels are not on and a few other best practices settings should be configured at first and tested.

My recommendations:

1 - Create an AP template and new radio profiles.

2 - In the radio profiles make the following changes:

Reduce radio power to 14 at first, test and see if this needs increasing or decreasing further
Change floor setting to 2
Max drop to 6
Enable DFS
Change the channel width to 40MHz
Under advanced settings, enable Weak Signal Probe Request suppression: Leave default value at first and increase gradually. If floor SNR over 90 days is let's say 30, set the value in the field to 20 and test.
Uncheck:Enable Frame Burst
If 802.11ax is required, enable OFDMA and check both Uplink and Downlink

Save and push a Complete config update to the APs. Above is the 5GHz radio but you can use some same parameters on the 2.4Ghz radio.

Again above are best practices but if in doubt, contact us directly.

BR,

To resolve connectivity issues, check for interference, verify network settings, update firmware, and consider upgrading equipment. Document troubleshooting steps and seek additional help if needed.
