I have 2 XRS4500's & 1 XRS 4900. I use the same provider for all 3 and they are all wireless. the 4500's freeze on a regular basis (at times every 10 to 15 seconds) but not the 4900. I disconnected a freezing 4500 connected the 4900, no freezing. Is connected to the same tv, cables, internet, modem/wireless router (due to location I need to connect with WiFi) and provider server. Any suggestions as how to correct this (without buying a 4900) would be appreciated.
Thank you
