Hi, That sounds like a PC issue... Did you install all the MB drivers?

mlhifi wrote I will open a ticket with TP-LINK and see where we go from here. Please, give their answer here, it's an interesting issue...

Hi, Your modem has probably a lease time set to 45min. You should use a Static IP instead...

Hi, For your issue, I suggest you to test again with Acrylic Wifi which is much better than inSSIDer. Probably, the situation will be the same so I suggest you to open a ticket with the TP-Link...

No, only Netgear and Asus did it !

Hi, Check the antennas, but your router seems defective...
