This router was bought only four to five days ago. It still has one year of official warranty from Global Brand PLC along with the cash memo. If anyone wants to buy it, you are welcome. I am selling it because it is not properly covering two flats side by side on one floor of my old building, which is around 2500 to 3000 square feet, and I want to upgrade. However, for my usage, it easily covers about 2000 to 2100 square feet, penetrating all wall obstacles. Both its 5GHz and 2.4GHz ranges cover 2000 square feet perfectly. Anyone who wants can take this. I bought it for 2200 Baka. If I get 2100 Taka, I will be able to upgrade to a new router, and both the cash memo and warranty are with me. You can also check it extra before buying.
