VMG3925-B10B drops 5GHz wireless several times a day - HELP!
Hi guys,
Turning to this forum as my last resort.
I recently got fiber installed and along came the Zyxel VMG3925-B10B router.
I registered both a 2.4 and a 5GHz wireless through the router without problems. I used the same password for the two networks.
But, for three weeks now, my 5GHz wireless keeps on failing several times a day, so that I have to restart the modem in order for it to work again. This is not popular in a family of 4.
The SSID is showing but when I try and access it via an iPhone for example, is says "Wrong password" even though it is the correct one. I can tell when the 5GHz is failing as the internet connection is inaccessible. Sometimes the SSID is not even visible as a wireless network.
The 2.4 GHz is not affected at all, which is very strange. But I want the speed of the 5GHz for a couple of my devices.
My provider has been abolute sh*it in providing a solution as they have never encountered the problem they say. Evrything looks good at their central. They are having me try to turn off some of my older devices like an iPad 1st gen to see if that helps, but it hasn't.
Router has latest firmware and everything - I've checked. And I also recived a new one, because this was also happening on the previous Zyxel router (same model).
I previously had a Sagemcom Fast 3890V2 router from my previous provider through a coax connection without any wireless problems at all, which makes me think it has something to do with the new hardware.
Do I need to configure something in the router, missing a check mark or something - I am at a loss here!
Sorry for lengthy post - but any help will be greatly appreciated.
Thanks.

Hi TJcph,
May I know it need to take how long for this “5G WLAN not be associated” happened ?
Is there a lot of traffic generated during this period ? How many clients connected to the router at that time ?
In order to provide you with a better assistance, we contacted you through private message to get more information, please check your message box.
@Zyxel_Support_CPE please post any guidance here, not just in PM. It seems to be a general problem with the router?
Hi Ptillegr,
Can you describe more detail “5ghz is very unstable“?
WLAN client can connect via 5G SSID, but sometimes traffic will be drop? Or 5G SSID disappear? Or other situation?
And please also share the firmwave version of your device.
Best regard
michael
i have the exact same issue and my router came with Firmware Version: V5.13(AAVF.11)C0_20180409B.
i have also downloaded V5.13(AAVF.12)C0 and tried to upgrade the FW, but it always rollback to the old FW version after 2-3 reboots.
Even during the short period the router running with the newer FW, AAVF.12, the 5G WiFi still disappeared after 3-4 hours regardless whether I logged on to 5G network or not. That’s also the reason I have to reboot the router to bring 5G WiFi back, which caused the FW rollback after 2-3 reboots. Really annoying!
meanwhile, 2.4G WiFi works just fine.
can you please also send a new FW to me?
thanks in advance!
Happy new year btw!

Hi Toxiaxia,
The latest generic fw is V5.13(AAVF.12)C0, we expect to have next release on March/E.
You mention device will rollback to older version after 2-3 reboot. So did you try to reset your device after upgrading to V5.13(AAVF.12)C0? I am not sure if you ISP is control it keeps in older version or not, can you please ask your ISP for this?
I rolled back to the earliest firmware still available and have the same issue. Is it possible to allow access the the older V5.11(AAVF.3) firmware which was more stable?
VMG3925-B10B next firmware release schedule is postponed. I send download link of 3C0 firmware to you, please help to check your inbox.
I tried toggling the network off/on, I even reset to factory defaults and tried setting up my old SSID and password. I did not, however, try and see if the 5GHz network worked with the device defaults, because all my devices are already set-up to my own configs.
I downgraded to 5.13(AAVF.11)C0 and so far no issues again. Let's hope it stays that way...
I have the same issue, however downgrading to "5.13(AAVF.11)C0" didn't help. Can the same magic FW as SteveRouter got?
Thanks!
