I currently have ADSL from talk talk. The router I am using is an old THOMPSON model. Unfortunately the wireless only just reaches the rear of the property....I tried a belkin n wireless modem router PM01523uk which says it has the greatest coverage. It actually reaches outside the house and halfway down the garden.....although it refused to connect to just one wireless device, a usb wireless adapter, saying the password was wrong......... ( ultimate aim is get internet in the barn at the end of the garden )
My first thought was to get an extender positioned just inside the rear of the house with the belkin router. However whenever I look at 'amazon' reviews for networking equipment, generally, there seems to be as many bad reviews as good reviews.....also I now understand that an extender actually loses half of the bandwidth.....I struggle as it is with a phone adsl connection. Then I found that possibly an access point might be a better option. Can run an ethernet cable from existing router ( Thompson or belkin) to the barn, then connect using a wireless access point. As I understand it, I would not then lose any bandwidth.....it would be better if the access point had the same 'SSID' as the router to give better continuity when moving mobile wireless devices ( unless I am wrong or this is not possible). Again choice of access point device is difficult. The TRENDnet TEW-750DAP Simultaneous Dual-Band Wireless-N Access Point (600Mbps) has been recommended. I think my Thompson. And belkin routers are more than likely only 2.4 ghz......but if I get a dual band that will hopefully future proof, in case i get a better router later.
There was a further option i considered, getting a super router which would make the journey to the barn on its own....again reviews confused me.....it would need to travel...30 feet to the rear of the house through three brick walls, then outside it travels in open air for approx 50 feet through a wooden wall to the barn.
Sorry for such a long question......but can't see the trees for the forest....
