I am personally using this device from the past 2 and half years and it has never never disappointed me. This is a really good wifi router with a really reasonable price.It has a decent and good wifi range as well as a good link speed.Other companies do not make products with dual antenna within this price range. It does not support dual band. It works only at 2.4ghz band. The dual antenna is for increasing the signal strength.Not only that this router has a quick and easy installation and setup process. The speed and functionality offered at just about 1k is the best you can get from any brand.Also the quality of the router is amazing and the range is pretty decent. Overall I would say that If you are strict on budget then this router from TP Link is the must buy.
