I buy d link wireless router and set to my home.Before 1 month its was veru good speed then after 2nd month its speed was very slow.Its Download Speed Was Only 50kb/ps.And Suffering is Good.I contact costumer care and costumer suppkrt says your problem is solved and your speed is fast.
Then I browse internet Then Speed Is Slow As Well As Before.So I return this dlink wireless router and buy a new one.
