GL-AXT1800 - WAN port: "no cable detected"

Technical Support for Routers

Hello, I'm having some issues with the WAN port of my GL-AXT1800.

I'm trying to use it in a hotel, connecting to an ethernet cable (terminated in a RJ45 plug) provided for laptops.

Whenever the port is set in WAN mode (DHCP), every attempt to make it work fails, it always returns "no cable detected" and the only way to use the router is in repeater mode with the not-so-good hotel Wi-Fi.

I'm pretty sure the port is not bust: I already tried to switch the WAN port into a LAN port, and it starts behaving as expected, I can 100% use the client connected on the port, the only failure is in WAN mode.

I'm also pretty sure it's not an issue with the hotel ethernet, as I have a Beryl 1300 (as a backup unit) and in this one the WAN port works as expected in the exact same hotel room.

My AXT1800 is running on the latest firmware available (4.6.8), I also tried a full reset as I thought maybe there is something wrong in the configuration somewhere (after several upgrades since I bought it almost 2 years ago) but even that didn't help solve the issue.

Would really appreciate any help, thank you!

Hi,

  1. Is the AXT1800 used attached power supply?
  2. Please try changing a new one network cable to check again.
  3. How about the WAN status of AXT1800 if it connects to LAN of MT1300?

Hi Bruce, sorry for the late reply

  1. yes, the original 5V 4A black power supply provided in the box
  2. can't use a different cable, this one comes out of the wall and ends with a RJ45
  3. it works, the AXT1800 takes the DHCP lease correctly from the MT1300, using a very short ethernet cable (like 30cm)

I solved in a very quick and easy way: bought a super el-cheapo 5 ports gigabit unmanaged switch, connected the hotel ethernet and the WAN port of my AXT1800 to that, and now it works.

Maybe the MT1300 has a higher "sensitivity" to the cable, or the cable is crap quality or too long/with losses, but at least now I can use the AXT1800 WAN port even though I have to carry an additional device with me :slight_smile:

Thank you very much.

Thanks for your update.

Even it can be workaround solved by a mini gigabit switch as possible, but the network interface ends with RJ45, s we don't know if there is a defect in the middle of the network cable (example in the 8-core cable, only 7 cores are working).

It's not that the AXT1800 is pickier than the MT1300, like the AXT1800 may have higher negotiation requirements than the MT1300 when the PHY negotiates the rate.
