I'd like to share some information and alaso wondered if some kind person could give me some feedback to the setup I have.
On upgrading from ADSL to VDSL the dilemma I faced was getting enough coverage to Building 2 (Ref Fig1), as the VDSL Modem didn’t quite have the range I used to have using the ADSL modem. After install we noticed that the WIFI from the VDSL Modem seemed to stutter occasionally, especially noticeable during WIFI gaming. Download and upload speeds were ok over WIFI, 9mb dl and about the same up. Speeds over Ethernet were a vast improvement from ADSL 12mb dl and 0.8 up to VDSL 28mb dl to 9 up, even the ping improved by a few points. I tried searching for a compatible WIFI extender for the TG589vn v2 but failed, also read about others having stuttering WIFI issues like I mentioned with the TG589vn v2.

So I decided to try and use the redundant equipment I had like the ADSL (DSL-2740B) modem as a router attached to the new VDSL Modem (TG589vn v2) then used its WIFI sender to reach the compatible WIFI extender (DAP-1150) and turned the TG589vn v2 WIFI off. (See figure 1.) The DAP-1150 refused to WPS with the TG589vn v2.
It all seems to work but it was good luck than good management and I am not sure if I have made use of its full potential. However the DAP-1150 WIFI does not stutter during gaming like we noticed with just the TG589vn v2 WIFI, but the upload and download speeds are significantly reduced, even tho they are acceptable, at around 4mb dl and around the same up.
My networking skills are very limited and I simply reset the DSL-2740B to factory settings, changed the SSID and WEPA key, used the WPS to pair the DAP-1150 and connected the DSL-2740B to the TG589vn v2 via Ethernet cable. I’m sure if all connections were used in (figure 1) it would fall over but only the Green connections are used at the same time.
I can see the same submask on all devices is 255.255.255.0 and there are no static IP’s anywhere, between all 3 devices the Modem, Router and WIFI extender all seemed to handle the configuration between themselves.
My questions are:
Was there a better way to set this up?
Should I try and understand Bridgeing? (Heard someone discuss this in a post but my knowledge on this is zero, don’t even know what it is.)
I would appreciate any comment as I feel so very nooby around networking.
Thanks for reading.
