A couple weeks ago Time Warner sent me an email that they were offering a free upgrade to my Turbo Internet service which was 10 meg down / 2 meg up. The new speed is up to 100 Meg down / 10 meg up.
I got the new cable box which was an Arris DG1670A Docsis 3.0 Gateway.
I connected it up and shipped back the old cable box to Time Warner.
The Arris is a combo cable box and router with built in Wifi and 4 Ethernet connections. I tried to configure it so that my Netgear nighthawk router would stay the same, but no luck. Called Time Warner and the tech configured my Arris to just be a GATEWAY instead of a router and all is working.
Speed tests are variable, but using the speed test from timewarner I have been able to see over 100 meg down and 11 meg up when connected to server 01 - Austin Texas. Server 02 and Server 03 have been slower.
speedguide.net - 3 down, 4 up
Speakeasy.net - 14 meg down, 10 up
speedtest.net - 71 meg down, 10 up
I set this up on Friday and on Monday, IBM's standard software installer pushed an update to my machine that was taking forever to complete. It actually failed 2 times and on the 3 time, I watched it closer and did a full upgrade of the software, but it took over 7 hours to finish. I went and did a test with Free Download Manager and downloaded a 20 meg file off of our file storage system. Data was only coming down at 20-30k. I might as well go back to a phone line modem...
These were things I tried to resolve this issue:
1) I was using the AT&T network client 8.2 (I think it was) and saw some posts in the forum of similar issues so I upgraded to the V18.104.22.16801 client and reran the test. No luck
2) I tried changing the MTU size on the AT&T Net client. No Luck
3) I tried using the optimizer tool on http://www.speedguide.net/ . No Luck
4) I tried changing the default network setting to Both the Internet and my company's internet with Managed VPN - IPSec. No Luck
5) I tried changing the default network setting to Both the Internet and my company's internet with Managed VPN - SSL DualAccess. Bingo - 400-800k down
Now, I don't have anything documented of VPN speed before I put the new gateway box in place, but I know I was not experiencing 20-30k connections.
Hope this helps someone down the road....
