TM500 S "no internet connection"

hello guys,
I have got this box, it works ok but in the lan menu, it says "no internet connection". i have tried almost every method listed on different advice forums, including of course, DW, but i just can't seen to solve the problem. i have flashed the original as well as different images onto the box( latest one running UR but to no avail. trying to flash bootloader just doesn't seem to work. i'm stumped. i know, if it ain't broke, don't touch it. but this one just sits in the mind and i want to see if i can cure it.
any help please?

There is issues with some images saying no internet connection but it still works.

thank you sir,
i thought so as well. as you said, the box works, updates via network and all, just says no internet connection.
oh well, as long as it does the job, well and good

May I ask how you are connecting to the net with your box. I also had issues when connecting via av plugs. A soloutution which worked for me was either 1) Connecting via Ethernet or 2) using a TP link nano router (wr702N)

So sorry for the late reply. Was busy with daily life. Anyway, I have the router and the box connected via an Ethernet cable. I haven't tried it with av plugs, didn't need to.
