Short Answer:
Slowdown caused by IPS being enabled in the RVS4000 router. Disabled it and got 124 downa dn 12 up on 2 computers...

-------------------------------------------------

I am trying to determine what may be causing the speed to be so slow at the computers.

I have a DOCSIS 3.0 Arris tg822g modem connected to a Cisco RVS-4000 4 GB port router (1000 Mbps connection on cat 5e cable per RVS 4000).
This then is connected LAN Ports:
(1)- Solar Edge solar inverters to feed data about the solar panels to the internet (100 Mb connection)
(2)- dlink DIR-655 - running as a switch 1000 Mb connection per RVS 4000
(3)- dlink DIR-655 - running as a switch 1000 Mb connection per RVS 4000
---- Off this I have a PC, Printer and another Router as a switch (Linksys E2500 4 GB ports)
---- On the Linksys I have Roku, Home server and DVD player connected
(4)- Belkin running as switch with printer attached and multiple wireless clients (port on RVS4000 says 1000 Mbps)

According to the RVS4000, ports 2-4 are
Speed Status: High
Duplex Status: 1000 Mbps
AutoNegotiation: Full
Low: Enabled

Port 1 is Duplex Status: 100 Mbps

If I connect a laptop directly to the router, I can get 123 Mbps from speedtest.comcast.net. If I go through the router I only get about 20 Mbps down and 11 Mbps up. The Comcast Blast is supposed to be 105 Mbps down.

I would think the port speed on the RVS would show correctly and that I should have maximum speed for a Gigabit network

Running LAN_SpeedTest from a computer hardwired into one DIR 655 to the home server
PC1 -> DIR655 -> RVS4000 Router -> DIR 655 -> Lynksys E2500 -> Home server
I get upload and download speeds of about 85 MBps, or 666 Mbps... So, internally it seems to be fine.

So what am I missing here?

Thanks for any input.
Phil

This article agrees with your findings...

Have you verified that you have the latest firmware loaded?

That is a REALLY old product -- the review I linked to was from 2007. I think we need to know what features that the current router has you need to give you a recommendation for a replacement. But if you need a VPN capable wired only router, look at a Linksys...

Since your network description uses the word "router" about 6 times it is difficult to determine where you are connected in your statement " If I go through the router I only get about 20 Mbps down and 11 Mbps up". You should start at the Cisco RVS and check speed at each step to the end points. Start with just the laptop connected to the RVS. Do you get full bandwidth? If not then there is your problem. Connect everything except the solar panels to the Cisco. Still work? If so move on down the line... Be systematic.

If these are real routers are you going into the wan port on every router? If so don't do that unless you are trying to segment your network. You should really only have 1 router and then just switches beyond that to have a clean network. Each router adds latency and is inspecting packets and depending on the CPU in each one can way slow down traffic. Like the other guy said plug into each device down the line and speed test. when you hit the problem replace or re connect not using wan on that device.

The only WAN port in use is on the RVS4000. All the other 'routers' are being used as Access points and only have cables in the LAN ports. DHCP is turned off for all of them. The network itself works, and I have no access problems, except for the speed, which seems to be stuck at 100 Mbps externally....

Also, if there was a problem, I would expect the longest route, listed above from PC to home server, would also be effected. But this test shows gigabit speeds, as noted.

Final testing results.
Tooks the DIR 655 out of the equation

PC -> Router -> Modem -> internet

20 down and 11 up

Finally took the Router out of the equation:

PC -> Modem-> Internet

124 down and 11 up...

Seems the RVS4000 is to blame, even with the Giganet ports connected at 1000 Mbps, it is the problem here...
Time to upgrade..

Any suggestions?

I don't need anything too fancy... even WiFi is not needed since the router is in the basement and I have 4 other access points throughout the house...

#1 is Reliability
2. Speed, not the OMG face melting speed, but better than the 20 Mbps I see now

Needs:
I have any where from 15 to 40 devices attached at any time, so it can't be a slouch that this many devices will over heat it and cause it to crash
I use Static IP's on about 5 devices and 15 VM's
I have 2 kids, would like to have time and site limits for them. The ones in the RVS4000 didn't work... It turned it off for them at all times, not just the scheduled times.

AC wifi would be nice though for future proof. I may get another router and use this one as an access point, and with most stuff now having AC, it makes sense to get this.

I don't do VPN. Have NO-IP for DDNS. I do port forwarding to about 8 devices/ports, but would like ability to have more (20+ ports to forward)

I think those are the main points.

I just read your article, and it mentioned turning off IPS... Turned it off, saved the setting, and just got 124.29 down, and 12.09 up.

You just saved me $150-$250!!!

This also explains the reason I got good speeds through the LAN SpeedTest before...

Thanks!!!

Firmware version is V1.3.3.5

1.3.3.6 was released Feb 2014. I will see if I need any of the changes... Don't need it as it is LAN update only.

Changes Since RVS4000 Firmware Version 1.3.3.5
•
Fixed an issue in which an undocumented test interface in the TCP service
was listening on port 32764, allowing
unauthenticated access to the device
from the LAN side
