Sys light on zyxel G4100 is off - Zyxel ZyAIR G-4100 Wireless Router (ZYAIRG4100)

The WAN cable may be too long.
Your ISP may have issues.
The router may be getting too hot due to inadequate ventilation.

Yes Zyxel nbg-416n does indeed support repeater mode but you need to make sure you have at least firmware version v1.00(USA.5)C0 and you can switch to that mode via maintenance/sys op mode.

Hold the reset button until the POWER/SYS light starts blinking. If the reset button doesn't work that way, you'll need the console cable to reset the modem..

You can master reset the phone. Contact your service provider to get the master reset code for the phone.

Hello kb_gimper,

The power light and all other lights blink when the ZyXel P-600 is initializing. The ethernet, dsl and internet lights blink when data transfer is detected. The lights are from left to right:
* Power Light
* Ethernet Light
* DSL Light
* Internet Light

There is a work around for this issue. The account logs can be sorted on date, which puts the latest entries on top of the pile, irrespective of the S/N.

Default Gateway 192.168.1.1 modem : Zyxel
p/d - green
eth - orange
internet - off Zyxel MODEM interface >> WAN >> Setup WAN >> UId & P/w >> Apply
Internet light will go Green

because of zyxel support only zyxel product only

You need to set up port forwarding, so your router passes the correct ports to your computer

For me to help more, I'd need your router model number, and you need to find out what port the program uses (there might be an option to change the port in the program itself)
