Hi, I have a 300mbps rputer and a 150 mbps repeater. While connected to the repeater my speed will be of 150mbps or 75mbps?

Based on the specifications it's not clear, they simply state up to 300Mbps which is in truth the theoretical speed of a single radio 802.11n specification. The big gotcha of trying to buy an extender/bridge.

The single and dual radio models state up to 300Mbps, while it's true, only the dual radio models will not reduce throughput by a minimum of 50%.

As far as the bandwidth is concerned, why would it matter if you were operating at 300Mbps,150Mps, 75Mbps?

See specifications of products
Single Radio 802.11n @ 150Mbps (50% of 300Mbps):

(See note about connecting while running as repeater)

Dual Radio 802.11n @ 300Mbps (100% of 300Mbps):
http://hawkingtech.com/products/hi-gain_wireless_networking/range_extenders_&_repeaters/HAW2R1.html

The dual radio model wouldn't need to alternate between Client and AP as the one radio is dedicated to receiving, while the other radio is dedicated to broadcasting.
You do lose some speed but not near the 50% bandwidth most complain about.

Outside of some enterprise-grade routers, your average wireless router has only one radio. It cannot receive and broadcast simultaneously. Therefore, it must receive the signal first, and then switch to broadcasting, and then switch back to receiving, and then switch back to broadcasting, and so on. Consequently, the one radio can devote only half its time to either role.

As a side note, radio and antenna are not the same things.
Lots of routers/repeaters will have 2 or 3 antennas, this does not mean they have 2 or 3 radios.
2 antennas may be connected to one radio while the third hooked up to a second, etc.
Always read the specifications of the product before you buy.

So this router/extender should work. Am I right?
