Task of TP should be to act as wireless + LAN switch and the gateway to let everything settle further.
After numerous emails with the TP-Service was the solution to adjust the unit in the same IP range as the other devices and the gateway,
so the Internet is accessible. Unfortunately, this TP is no longer on the client to use, as they are in a different IP range.
Furthermore, the router can not spread via DHCP IPs to the wireless client then. A guest network is not provided in TP.
Ultimately, one week back and forth, a lot of work and trouble.
As a router, the device is certainly good.
I ordered a Netgear router to compare. The facility has taken 20 minutes now run Internet access, WLAN DHCP and guest access.
Since TP must still abgucken what.
The service of TP is great however, so even 2 stars.
