Thanks for the tipp on disabling the IPS, I did it and the speedtest.net test resulted in 21Mbps.
So, it is already a great improvement.
It is interesting though, that on the IPS page of the router, all four protocols were disabled (http, ftp, telnet and rpc), so I am not sure if it was doing anything useful anyway. Am I right?
Since the tech from my ISP was using speedtest.net for testing and did get 25Mbps, I figured that it should work for me too. I am not sure if our ISP has a website for the same purpose.
In order to eliminate any bugs I was considering upgrading the firmware on my router, but I am not sure which firmware I should use, it seems to me that there are two sets of firmwares available for my router one with VPN version 1.xx the other one is VPN ver. 2.xxx
The model# of my router is WRVS4400N v1.1 but I am not sure whether to upgrade to one or the other VPN version is up to me or the VPN version range is already set in my router and I cannot upgrade to 2 from 1 in case I have VPN v1. (How can I tell which version of VPN I have on my router?)
8 hours later I added this text:
I did another test on speedtest.net and at this time I got 24.35Mbps, so you were right, speedtest.net won't give you a reliable speed value if you just run it once and you want to make a decision based on that. (Btw., I contacted our ISP, they don't have a net speed measuring website within their own network.)
So, I am done with the speed problem thanks to your right on target suggestion, but could you please, answer my other two questions:
- Was the IPS in my router doing anything usefull to me since all 4 protocolls were disabled - until now?
- About the firmware dilemma.
