Hitron CODA 4582U UI hangs when adding MAC addresses (Managed Devices)
I have just upgraded to Ignite Gigabit, so have just deployed the Hitron CODA 4582U modem/router. Previously I had been using a pure modem (don't remember the make or model, but it doesn't really matter) and my own router (Linksys EA6400). I had done significant configuration on my router, including MAC address filtering to only allow specific systems to access the network (a list of about 20 entries).
I am now trying to add my MAC address filtering entries to the Hitron device.
All goes well until I have added 11 entries. When I try to add the 12th entry, when I click on "Save Changes", the UI completely locks up and never comes back. The only activity on the page is a 'busy' spinner with text "[PENDING]" and "Saving changes, please wait...". Every few minutes the browser reports that the page in no longer responsive.
The only way I have found to recover from it is to reboot the router (power it off and back on). The router itself still seems to be working, only the UI hangs, but still, without the UI I can't add the remaining MAC addresses.
Yes I have verified that it is not a browser issue (happens on both Chrome and Firefox).
I am tempted to try to bridge my old router back into the network so I can use that for my MAC filtering, but would prefer to consolidate into one device if possible.
I'd appreciate any help in resolving this UI hang. Thanks in advance.
As a person who doesn't like clutter or tangled wires all over my own desk, I can certainly appreciate wanting to consolidate everything down to 1 piece of hardware.
I ran into a the same situation as yours back when I had the Cisco DPC3825 and wasn't able to find a work around. I may be wrong, but it seems to be a limitation of the gateway. Once I tried to input the 11th entry, I had the same problem, where it wouldn't save my entry and instead would just loop, 'saving the settings'. I had to resort to bridging my modem and using my own Asus router.
I'll tag in a few of our Resident Experts and also invite our Community to chime in to provide some guidance. Realistically though, I think you may need to implement your external router to accomplish what you're looking to do here.
I believe this is a firmware bug. However with MAC Filtering it can easily be bypassed by cloning the MAC address. These best security is WPA2 with AES Encryption, I wouldn't bother with MAC filtering.
