As some others in this forum, I've purchased a pre-owned RUT240 with WiFi connectivity issues. When moving 3-4 meters from the router the ping from the 

I've already:

  1. Upgraded the router to the latest firmware (RUT2XX_R_00.01.14.4_WEBUI.bin)

  4. Checked that the antennas are connected properly and to the correct connectors
  5. Checked that there are no visible defects in the antenna connectors

  • Another client is connected to the router via the Ethernet
  • The test client is pinging the router (192.168.1.1)
It appears that there is no visible difference in the wireless data when looking from the test client:

I've attached two screenshots from the router web UI taken when the ping is getting and not getting through.
Do I have one of those defected devices your customers have found and reported in the forum? The batch number of the device is 093.

Hello,

I would recommend returning your RUT240 to your reseller due to hardware issues. I sincerely apologize that you received one of the faulty routers.

Bets regards.
