Dear All, I have received my probe yesterday morning (V3, like shown on https://atlas.ripe.net/docs/probe-v3/ ), connected and registered it. Unfortunately, not only no measurements or IP address information appeared in my profile after waiting several hours, but there's no Ethernet activity from probe at all, even in the packet trace. Things I tried: * 3 different switches (Fast and Gigabit types); in all cases a notebook running either Windows or Ubuntu when connected into the same socket acquires IP address just fine and can browse the Internet. * 3 different LAN cables; in all cases switches detect 100 Mbps physical wire but nothing more. * 2 different DHCP servers as well as wireshark on direct connection. * 3 different power sources (1A phone charger, notebook 2xUSB, PC USB). * Removing and re-inserting the USB flash key that came with the device, dd'ing its contents to a different USB flash and inserting it instead (dd finished successfully). Every time after the boot sequence ends first light glows steadily and adjacent one blinks slowly, like it is supposed to be according to https://atlas.ripe.net/about/faq/#what-do-the-lights-on-the-side-of-the-prob... . Looks like the interface just isn't up in the device OS. Is there anything else I can check? Should I request another probe? (it took more than month to receive first one by post) -- With Best Regards, Marat Khalili
