Macbook Pro remains connected to AP230's but No Internet Access

[dgillespie]

If the user disconnects from the wifi and reconnects then he will have internet access again but he has to do this a couple times an hour. It's an older macbook pro but it is utilizing 5G. Has anyone run across this before?

Here is are some sample logs with the error highlighted:

@kevin.piazza@sglassman yes, the firmware downgrade fixed the issue for the Macbook but it still remained for a few windows clients.  I haven’t been able to test further since we are all working from home these days.

Hi,

I had a similar behavior like this with one customer I met:

when a client is situated in a middle proximity between two AP's, without moving it can roam between both AP's causing the internet to drop.

Not sure if it was exactly the same issue as yours seem to be relevant for just few devices... they had very long beacon intervals (300 TUs, should be left default 100 in 99% of cases) and DTIM increased to 5. So the stations were allowed to sleep for about 300*5 = 1.5 second. Most likely because of that, every single minute a station standing in between two APs (-70 dBm RSS from each) was losing throughput down to 0 for 5-10 seconds and then finding the second AP. And after about a minute the same scenario and moving back to the first AP. Also site survey tool was showing BSSID graphs quite “chopped”. When we decreased beacon interval to 100 TU and DTIM to 2 it became normal.

Hope that helps,

Tomasz

We have all kinds of Apple issues with our AP650’s.  @dgillespie any luck on the firmware downgrade?

[sglassman]

I am curious, did your downgrade to 8.4r11 resolve things?  We have the same issue on our AP230’s running 10.0r8 so I was just curious if it was resolved and came back or maybe our issue is not related to what you posted.

[dgillespie]

I downgraded all 3 WAP's to 8.4r11 and will test Monday.
