Re: Broadband Speed Check

Stats look ok to me. How are you testing the speeds - wifi or wired? What device? At speedtest.net?

--------------------
Services: HD TV on VIP (+ Sky Sports & Movies & BT sport), x3 V6 boxes (1 wired 2 WiFi,) SH2 in modem mode with Airport Extreme Router. On VIVID200, Talk Anytime Phone, x2 Mobile SIM only iPhones.
