XBox and Wii issues with trimmed beacon / basic rates

Hi everyone,

 

I have a customer that is NOT using AirGroup but is trying to trim the basic and beacon rates on their 2.4GHz settings of their SSID profiles. When they remove the try putting the basic rates at 11 and 12 and the beacon rate at 11 the Xbox we are using asssoc and auths succesfully to the OPEN network but doesn't get a DHCP offer made by their DHCP server. 


The debug of the client and network DHCP subcat shows the DHCP request being heard and a DHCP address being offered but the Xbox doesn't get the address. 

 

If we put the basic and beacon rates back to 'default' everything works. 

 

Obviously customer is trying to optimize the 2.4GHz settings to squeeze every last drop out of the spectrum. 

 

Any ideas????

Most of my customers have ditched support for the original Xbox and Wii
because of this and trimmed back to 12.

Re: XBox and Wii issues with trimmed beacon / basic rates

Since I have customers with large deployments of trimmed rates that are successfully supporing those devices, I thought it may have something to do with AirGroup?  The lack of AirGroup at this customer is really the only difference. The customer supports dozens of these older devices so dropping support is really not an option.

 

The device is an Xbox and it does get assoc and auth'd it just never receives the DHCP address that's been offered.

AirGroup has nothing to do with association or datapath. I would open a TAC case. We'd only be guessing on here since we don't have information about your environment. 


Thanks,

Re: XBox and Wii issues with trimmed beacon / basic rates

As an aside, TAC was able to steer me to a more generic doc regarding trimming rates. It had some findings in there about Xbox and Wii that I think is worth noting.

 

I tested the g-basic and g-beacon rates, per their recommendations and it works fine btw.

 

We will test the Wii tomorrow but the Xbox supported these rates:

 

wlan ssid-profile "ssid-XXXXX-Wii-TrimmedRates"
essid "XXXXXX"
a-basic-rates 12
a-tx-rates 12 18 24 36 48 54
g-basic-rates 5 11
g-tx-rates 11 12 18 24 36 48 54
max-clients 255
wmm
wmm-vo-dscp "56"
wmm-vi-dscp "40"
wmm-be-dscp "24"
wmm-bk-dscp "8"
mcast-rate-opt
g-beacon-rate 5
a-beacon-rate 12

Hi Everyone!

 

As a follow up.....

 

We had some really old Nintendo Wii's with ancient 'g' cards that just wouldn't connect if we trimmed the 2.4GHz basic rates and set the beacon rates. Here is the config that we ultimately ended up going with so that everyone could get on.

 

wlan ssid-profile "ssid-xxxxxx-Wii-HD-Dense-Hard"
   essid "xxxxxxx"
   a-basic-rates 12
   a-tx-rates 12 18 24 36 48 54
   g-tx-rates 11 12 18 24 36 48 54
   wmm
   wmm-vo-dscp "56"
   wmm-vi-dscp "40"
   wmm-be-dscp "24"
   wmm-bk-dscp "8"
   mcast-rate-opt
   ht-ssid-profile "ht-ssid-HD-Dense-Hard"
   a-beacon-rate 12
