I had lots of problems initially, mainly due to Mweb's inability to diagnose issues. Basically, when the router was plugged in, certain sites worked (twitter, google, etc.) while others (news24, mybb) redirected either to an Mweb error page or a landing page stating the router was still being provisioned.
Eventually turns out that 'Telkom does not pass my phone number on to Mweb' and therefore they were unable to provide the router with my Mweb account details. Once this was done manually it worked.
So for me, the process was definitely not plug and play. Also, the extender seems a bit iffy on WPS. I plug it in where I want it to be, access it via the ethernet port and a laptop and configure it manually.
Router access: 192.168.1.1 admin/admin
Extender: 192.168.2.1 admin/1234
The WiFi on the Technicolor router seems to be stronger than the Netgear DGN2000 I was using. In terms of range it reaches a little further, but the throughput seems better than my previous setup of the DGN2000 with DGN834 as repeater.
The extender is not very strong. I currently use it to feed my Mede8er 600X via ethernet (since this model won't recognise the wifi dongle that used to work with a previous mede8er model).
