Last week my BTU (located in my living room) + L7 NR2000 router (located in my room) after 7year usage finally spoil. Call TM and they replace a new modem router all in 1 Netis DL4480V1. Since my house is high-rise with copper wired that is the best they can give. Is it true? Because my room is abit far from my living room wifi 2.4ghz signal abit weak. Can i configure the Netis as BTU and add-on a new wifi router?
