FS#412 - WNDR4300 - It is not possible to upload firmware (sysupgrade) by LuCI-LEDE-17.01

----------
Unfortunately I can not use a serial connection type to fully log the whole situation when trying to install the new firmware - log starting when already can upload the new firmware sysupgrade.tar (via ssh) adds nothing to the topic and there's nothing there, what would could show any errors. Rosądne The only explanation is that the firmware is the type of legacy, so rather the same mechanism upload dopatrywałbym the problem (mtd). Anyway, until then upload the network is working again, and will mark a notification for closure. However, the problem can come back and then open it again even said frankly - I have no idea how to effectively log the same upload firmware and test its upload on the target device - because this is what shows the viewer that only indicates that the device deliberate suddenly becomes unreachable - or reasons They may be hundreds.
