Subscribers are = switching from crummy Comtrend or ZyXEL DSL modems (whose PPPoE = interface runs at 3 to 20mbps) to Calix GigaCenter equipment with = symmetric ISP link speeds starting at 25mbps on up. The complaints I've started to hear are that the new Wi-Fi signal "is = weak" - not reaching as far as the DSL equipment did, and that speeds = are abysmal (one report is 2.4mbps down, 0.25mbps upload).=20 Before I insert myself into the "unhappy customer" loop, I would like to = ask this august group for thoughts about things to check/test programs = to run/phenomena to consider. I would first do the following "easy tests": - Check for conflicting/overlapping Wi-Fi channels. I am fond of the = free app, WiFi Analyzer from farproc = (http://a.farproc.com/wifi-analyzer) for this test, but there are = several similar Android apps.=20 - Compare the signal strength for the DSL modem and the Calix modem, as = shown by WiFi Analyzer=20 - Be sure that all computer(s) are using the Calix modem. - Use a variety of speed tests: DSLReports, Fast.com, other favorites? - Compare speedtest results when the test computer is close to, or far = from the router. - (If possible) compare the performance for both Wi-Fi and Ethernet - Shut off the DSL modem on my way out the door to be sure it's not = causing interference or confusing the situation. Anything else you'd recommend? Second, are there other more fine-grained/analytic tests that I could = run? I'll have a Linux or macOS laptop that I could use to look at other = measures: retransmits, CRC errors on the Wi-Fi link, etc. And, finally, = what do I recommend based on the information gained from those tools? Many thanks. Rich
