I have a D-Link DSL 2750U wireless router for about a year now. It's been working as good as new till now. I purchased it for about 2500 and it has a very good range for connecting from one room to another. It has good connectivity all over your house.
It has a speed of upto 300 Mbps which is very good. It has a encryption security ranges from 5 variations. I personally use the WPA2 encryption security.
The modem link page can be customised in many ways. It is very easy to setup. Also it has feature to enable or disable some of the features.
I'm using this router day and night it gets heated up but the performance you get is the same without any lag. You can use this modem without switching it off for a long time. It's worth the price and can satisfy and you won't be disappointed with this modem.
This modem is suggested to all go and bye if you are looking for a good modem in your house.
