I have a RVS4000 with firmware version 22.214.171.124. Having read that throughput on the RVS4000 is reduced with IPS enabled, I tried disabling it with the following somewhat strange results: the download rates for a speed test done on speakeasy increased substantially as expected, but the upload rates decreased. A test done on whichvoip showed decreases in both upload and download rates.
To try to have more consistent results, I ran the first speakeasy test, followed by the first VOIP test, then the second speakeasy test and the second VOIP test. Then I disabled the IPS and repeated the tests. Wondering if anyone else has noticed something like this before.
