@Home24 

OK, there are some different numbers your posting.

The C20 has the 'capability' of 300Mbps on the 2.4Ghz band. The true speed will be what your ISP supplies, and that would be 200Mbps, no more, and usually less.

Now some other questions. This is wireless of course, and there are other things that come into play. Such as the DEVICE connecting.

So, what is the device, make and model of the device and if it is a laptop or PC, the wireless network adapter used, all this is needed in.

As is if you had better speed before, and if so, how did you get that, different router, modem, etc.

Do you have a WIRED connection, what speed does that get?

Have you done any debug, changed channels, security, checked on more than one device, etc.?
