I have a DYNALINK RTA1025W (ADSL2+ modem/4-port router/wireless), the wireless signal is low at the other end of my flat so I was thinking the cheapest method to increase the wireless signal strength is to replace the DYNALINK RTA1025W with something that has a stronger wireless signal. Can anybody suggest a product that has impressive wireless signal strength? Don't want to use Ethernet over LAN adapter’s cause of the price & the limited amount of power points in my flat.
