Flash firmware TP-Link TL-WR741ND rev 4.24

[Milan Horák]

Dobrý den a děkuji.

Postup bohužel pro WR741ND nefunguje (ani jiné IP rozsahy), nezbude než 
"instalace" sériového portu a flash přes tento. Na což si ale netroufám.

Byl by schopen mi to někdo za úplatu z okolí Havlíčkova Brodu (nebo 
poštou) spáchat?

Děkuji, Milan
