We just added an Airport Extreme to hopefully increase our wifi speeds (and actually stay connected which we couldn't do before). We have a modem through Brighthouse (our cable provider). Our Airport is connected with ethernet to the modem. The Wifi is turned off on the Brighthouse modem. According to Speedtest.net our download speed is about 180 but our upload speed is only 1.54. Not sure what other information to provide that would be helpful but any help would be greatly appreciated.
