3.9.42.9152 vs. 4.0.15.9872 and WiFi dropping

I have a small network at home with 3 APs, all a different model. I have a UAP, UAP-AC-LR and a UAP-AC-Lite. Recently I decided to update my Unifi software to v5.9.29, which came with the 4.0.15.9872  software for the APs. After I deployed that (it all went well), I found that my Nexus Player (the google streaming device) started dropping connections every 1-5 minutes (to any of the APs it tried to connect to).

 

The AP I wanted it to connect to is within 2 feet of the player, so was not likely to be a signal issue. I even forced the box to connect to the specific AP (UAP-AC-LR) by creating a separate SSID and only deploying it to thatUAP-AC-LR. and than setting up the player to connect to that SSID only.

 

I messed around with the uplink connectivity monitor but it did not seem to help.

 

After a whole buncg of tries, I finally put the 3.9.42.9152 version on the AP, since that's actually what's recommended in the info area of the interface. After I did that, my issues went away. I left the 4.0.15.9872 version on the other two APs.

 

Not sure if there's anything else I can do to track down the issue. I have not (yet) set up rsyslog, so I don't have the log data anymore.

 

I figured I'd at least report it here.

Uplink connectivity monitor is only for when you have wirelessly connected access points (mesh). If you do not have that, then keep that setting turned off.

 

I'm surprised to see this issue tied to a firmware version. But, can you post a screenshot of this page?

Hello @MichelvdL,

 

Are your SSIDs dropping?

Could you post your system config?

Re: 3.9.42.9152 vs. 4.0.15.9872 and WiFi dropping

Yes, I realize I did not need the uplink monitor, so it is now turned off.

 

IWRT the screenshot, 'm currently not at my house and the controller is currently turned off, so I'll try to get to that this evening. But there's no doubt in my mind that the firware version was the issue.

 

Note that I've used these APs without a hitch, with upwards of 50 different devices (phones, streaming devices, windows laptops, mac laptops, chromebooks, etc.) with the controller running both on Windows and Linux for years without ever seeing this.

 

If it seems like it would help, I can get rsyslog set up and capture the logs for both 3.9.42.9152 and 4.0.15.9872. However, that would likely be a weekend project, so that would be a few days before that's done.

Re: 3.9.42.9152 vs. 4.0.15.9872 and WiFi dropping

Are your SSIDs dropping?

 

Yes. The device will connect, work for a random period of time (1-5 minutes) and than drop and then re-associate (not great for streaming video). Sometimes it will actually connect to a different AP. Note that both APs exhibit the same behavior. It also appears to stick a bit to the last AP it connected to once that happens, hence my effort to add an SSID and force the connection to the AP I want.

 

As I mentioned in an earlier post, I'll try to get the other requested information this evening when I'm back home. I'm US east coast, so that will probably be 12 hours or so from now.

Here's the screen shot of the config. As you can see, the last AP uses the older firmware.

The major difference of 3.9.x and 4.0.x firmwares is that with 4.0.x, it has moved to LEDE-code base. It may take some efforts to re-evaluate the setup and iron out some hiccups. Just thought of sharing so u have better knowledge of how big this change is and what u are up against.

Hmmmm.....I see the entire setup seems to left mostly at factory defaults. Without understanding the positioning of the UAPs, I would say based on your config (leaving Channel and Tx Power settings to Auto if not a good idea), there is likelihood a significant contention of signal (at least for 2.4GHz) and the client devices (STA) would be 'confused' on which UAP to connect to.

Yes, it's all pretty much bog standard, I'm not an enterprise Icon Biggrin. The issue is not confusion about the SSID, since I have SSID '...-Upstairs' only on one AP (from that you may surmise the bedroom is upstairs). As I said, it would disconnect randomly until I backed off to version 3.9, after which things 'just worked' again. I'll just wait for a new version of the firmware, redeploy and report.

Re: 3.9.42.9152 vs. 4.0.15.9872 and WiFi dropping

Hello @MichelvdL,

 

Could you try the following radio settings? ( try to use different channels on each UAP )

Devices > UAP > Config > Radios

 

2.4 GHz
Channel width: HT20
Chanel: 1/6/11 | Choose one of these channels, a RF scan will help you choose the most clean one.
Transmit Power: Low ( Medium )

5GHz
Channel width: VHT40 | Optional VHT80/VHT160 might decrease wireless stability
Chanel: 36/44 | Optional (149/157) Choose one of these channels, a RF scan will help you choose the most clean one. Avoid using DFS Channels
Transmit Power: Medium ( High )

 

 

Could you post the UAP logs? ( please include the MAC address of your devices that have issues )

Glenn R.

I'll see what I can get done this weekend. A major snow strom coming my way, so that may snarl my testing a bit. If I get some of this done I'll post a follow up.

Re: 3.9.42.9152 vs. 4.0.15.9872 and WiFi dropping

Odd. I got an email note this topic got a reply, but I don't see it here. Anyway...

 

I haven't been able to do any testing on this due to a whole bunch of re-configuration of systems I decided to do last weekend, including moving my controller to a VM so I can keep it running all the time (I did not do that prior to all of this).

 

Since the AP behaves fine with the older version, it's not extermely urgent I deal with this, though I'll try to at least mess around with it this weekend.
