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

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.

Answer 1

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.
