I have the wmr88 (cable around 1m20 or 1m50) and a wifi dongle. It's an old raspberry (not sure which model). No usb hub. Maybe the wifi dongle take a little too much current? I cannot check in details, the setup is at my parents place, 150km far... I connect by ssh.
The setup worked fine for years. But I may have done some update recently (not sure if kernel or other relevant packages was part of it). I'll give a try with a hub, if I find one around... Otherwise, maybe replace the raspberry with something else. Thanks for your clarifications! Le dim. 12 mai 2019 à 19:42, Leon Shaner <[email protected]> a écrit : > Wysiwyg, > > Oh, then never mind.
