I have 3 computers one with a wireless router, connected to a wireless router connected to the wired router connected to the modem the wired router connects the other 2 computers 0-o on the 2 computers upstairs I have 100mbps and on the wireless router with a 54mbps router... 54 mbps. If I got a 100mbps router would it be 100mbps and would that technically double my internet speed?
