The router has no problems. I bought it 8 months ago and it works perfectly. It looks brand new and still has 4 months of warranty remaining. I purchased it from BCS Computer City, Agargaon IDB Bhaban. I will provide the cash memo and everything else that came with it. I am selling this to buy another one because I need a different range and speed. All security documents can be provided. You are welcome to check it before buying.
