Could our Wifi issues be down to our Draytek PoE?

hi guys

We have a load of Watchguard Access Points and they are connected to a Draytek 1100 PoE switch. This switch is then connected to our backbone switch which is a Cisco 3750.

We have set DHCP on the WiFi network that the access points are on in a way to be from 10.0.5.20 on wards and the management IP of this Draytek PoE being 10.0.5.6. Every single day, people complain about not being able to access the internet properly and then it fixes itself again. Then it happens again.

When they do complain, I end up not being able to access the management IP page of the Draytek on 10.0.5.6. This makes me believe that it is in fact this particular PoE causing the issues we are having.

Could that be the underlying problem?

Thanks for helping
Yash

How many users are using the  Draytek 1100 PoE switch.  ?

I would replace the switch with a Cisco, HPE, Ubquiti switch.

I'm afraid we have no trust in the inexpensive product line anymore. We moved away from it many years ago.

We found

1. over heating issues.
2. crashing.
3. DNS issues.
4. Memory buffer issues.
5. ARP issues.
6. Management Web Page crashing issues.
7. SSH issues.

list goes on....

I've logged on to the switch and nothing is showing in the logs for any errors. Which is the frustrating part. But i just wonder if you can't get to the admin page, there's evidently something going on with it?

Poor design.

Does it do it after many hours powered up ?

Put a timer on it, and power it off and reset it every 1 hour!

Yes, I figured it would be the case. Having to visit the scenario with a PoE Cisco as that would make a lot more sense. Andy, did you also us a Draytek before with all of those listed issues?

No, it depends how you get to the access page.
If that is through other equipment then other equipment can cause part of the problem.
(wifi signal dropping/ getting jammed, if you access the switch from WiFi).
If the AP's are powered through the switch is any of them restarting  due to lack of power?
too much power pulled from the switch?

A more complete picture is needed.   or is it a flat network and you are connected using the wired part.
With DHCP is leases are too long, or the pool is too small There may be a depletion of addresses ... (that should show up in logging on the DHCP server).  Which can be alleviated if you are hovering around the edge of a depleted pool.
(Addresses become available not when a device disconnects but rather when the lease expires).

yes, we binned it all and replaced it with HPE, Cisco and Ubquiti kit.

Draytek stuff is cheap, best left to home use!

Even at home i have HP Switches,  Omni-Turris as AP, and a homebrew firewall (with extra's).
