USG40W hangs upon small basic changes
I had my USG40 for a few months, only today I felt was a good time to test to put it as Router/Firewall on my network. Firmware is the latest 4.62. The device is found by ZON on W10.
The only port used is LAN1. It goes via a Patch Panel to my Ubiquiti EdgeMAX 24 Port Switch and via a second Patch Panel to my network ports. Everything wired, everything works, everything CAT6 UTP or above. I have built it all myself with some measuring tests and advice by a network technician I know from work, certified professional with years and years of experience and all the Fluke testing tools you wish you had but can't afford.
Initial configuration went fine, but the interface is kinda sluggish and it seems prone to hanging, also hanging my network.
During and after the Setup I had to change a few things.
- I turned off Wifi, I have an AP.
- DHCP Pool started at 192.168.1.33, I changed that to 192.168.1.2 since I have my switch on *.5 with a static address and my FileShare on *.10, also with a static allocation..
- I also expanded DHCP pool from 200 to 240 since I have my Virtual servers above *.230
I did all these changes in the Ethernet interface of "lan1" since there is where it goes and where I had it on my other Router.
Doing these the USG40 would sometimes gracefully accept them, and sometimes just hang, causing the network to fall out.
I also went into Wireless > AP Management to add my AP, or to see if I could manage its connectivity through there - it is an Asus device, not Zyxel - but every time I went to that place the USG40 hung, as mentioned before.
The DHCP never got around to even fully list network devices, I never got to see the USG40 working for more than 15 minutes at a time, and the ONLY purchased feature I actually activated via the Licensing was IDP, so I really do not get why it would hang at the above described actions.
This evil circle - setup > configure > change > hang > dead > reset > start over - was repeated with mixed results 6 times until I gave up.
I realize USG40W is not a performance choice, I bought it second hand, renewed the IDP license, and have been testing it on and off to check for any stability issues or anything that could have popped up browsing the interface and upgrading the FW. It should be able to handle a DHCP pool that I specify, it should be able to enumerate 15 fixed computers on a Wired LAN, but it doesn't. It has NO Wifi chewing additional resources. I have been following the manual as much as is relevant - all the 1162 pages from October 2020.
