have you input the correct wireless password during the setup process? If you unplug the extender, will your mac work with home wifi?

i think if the router is working fine we can ignore the errors. All ds lines has errors but that doesn't mean there is something wrong. And it seems that VR2600 doesn't support dsl up time display...

hi, can you change the time settings under settings--system tools? if there is no time settings, update the extender firmware first. You can also reboot the extender, it will get the correct time.

no ideas,but you can look for a router which can support more than 16 rules of virtual server.

hi, can you find the answer from the user guide. http://static.tp-link.com/res/down/doc/Archer_C7(UN)_V_2.0_UG.pdf ( page 4）

maybe firmware upgrade will fix that
