A:Answer There ARE issues in using the MR7500 with the original Velop. The original Velop will connect successfully with the MR7500 but there are two major flaws. The original Velop did not support 6ghz or WPA3. When you first install the MR7500 it will work great but once you add the original Velop you can find your speed drop considerably. This is due to the WPA3 protocol which is not on the original Velop. The MR7500 does not check for this. On the MR7500 you have a choice of WPA2 or WPA3 on the 5ghz band. On the original Velop the 5ghz band only supports WPA2. When your phone connects to the original Velop on 5ghz I have found an immediate speed drop since the parent node is also looking for the WPA3 protocol and it will not get it. So to correct t that issue you must make sure that you have WPA2 as the selection for your 5ghz band. Secondly, if you have the 6ghz band active, the original Velop will not see it. This has also caused problems. So until I upgrade my other original Velops, I have turned off 6ghz and WPA3 on the 5ghz band. This has solved the problems. Once I upgrade my old Velops, everything will work fine. I have the Samsung Galaxy S21 Ultra 5G. Without correcting the above issues, my speed was app. 100 down. Correcting the issues, my download was over 400. I’m using T-Mobile Home Internet and get speeds up to 500.
