Router reboots when ADSL comes online

I have a P660HW-D1 with the (currently) newest firmware: 3.40(AGL.4)C0. My router seems to boot normaly, the DSL light blinks and then becoms steady, then the Internet light comes on for a fraction of a second before the router resets.

Re: Router reboots when ADSL comes online

I have not seen this issue before and I work directly with this modem on a daily basis. If its under warranty, then get a replacement. If not... Test the modem with wireless enabled, but wireless security disabled.

You can change the firmware to that model but, as the hardware won't chage, you will be unable to connect the ISDN to a PSDN network. There are harware differences on both models.

Port forwarding not working in ok firmware AGL6 or later

According to my very thorough testing some weeks ago, P-660-HW-D1 port forwarding is really very broken.

The worst thing is that not only does the port forwarding work properly, it lets packets to LAN addresses where they're not supposed to go. This means you're not safe behind LAN.

Firewalled or not, AGL.6 or AGL.7 shouldn't be used at all in my opinion, they're unsafe. When in routing mode, and having several LAN machines behind one Zyxel switch port (i.e. separate switch attached), I found that the port forwarding is completely broken.

I have contacted Zyxel Finland about this issue two weeks ago, and they initially thanked for the finding and said they're passing the issue onwards and investigate it.

The best current solution is to downgrade to (also very buggy) AGL.4.

You may want to try updating your routers firmware, it seems like it's gotten scrambled. Here is a link for your routers firmware, click the 'Download' next to 'Description'
