@Ronele: You should be able to stream Netflix on a 2Mbps line - I know of somebody streaming via a Roku on a 1Mbps line using an MWeb 1Mbps Premium uncapped account. I would suggest that you first try a test account from a different ISP to see if there is any improvement. All of these ISPs offer test accounts. Choose those that don't require any credit card or debit order details.

If you did sign up for the Unotelly trial I would also switch back to that while you are running your tests as the DNS service can affect your streaming performance. You will not be able to access most of Netflix's international services apart from the US and possibly the UK (probably need to switch to a UK Roku account) using SmartDNSProxy. There is a lot of duplication amongst the different services but you will probably find a lot of movies and TV series of interest on the other services. You can switch between the different Netflix services directly from the Unotelly website and the Roku will automatically connect. SmartDNSProxy does not offer this facility as they presumably do not have servers in all of these countries.
You might have problems opening this link (SmartDNSProxy or Chrome problem?)

Use this site to find movies and TV shows - click the Netflix button to see where available (in this case UK and Ireland). Try to look for the TV series Suits etc.

If you give us some feedback regarding switching to a different ISP test account we should be able to offer some other suggestions regarding your line issues. The lowest Netflix resolution only requires a bitrate of 235kbps which is about 1/8 of your current linespeed. You could also try the BBC iPlayer diagnostics to test the streaming performance of your line ...

Look for a file on Netflix called Example Short 23.976. This gives the current bitrate in the top lefthand corner of your screen. It is supposed to slowly increase from a low of 235kbps to 375, 560, 750kbps etc. depending on the line quality.
