RVS4000-EU, Slow Internet Download

Hi,

I have read a lot of things about slow download speeds and the RVS 4000 router. The suggested solution to disable IPS didn't help me - the througput is still slow.

Internet Link: 50 MBit/s Down / 2.5 MBit/s Up

Testing I did so far:

Laptop connected direct to cable modem => full speed

Laptop connected to RVS 4000 => dowload drops to about 20 Mbit/s

RVS 4000 Config:

IPS disbled.

Firmware: Current 2.0.2.7

What else could I try?

Thank you,

Sven

Try to disable even QoS, restart device, perform speedtest.

I'm not sure when QOS is really disabled, but I set "Bandwidth Management" to disabled. Reboot was also done.

I think I have found the problem.

I did the following tests:

  • Reset RVS 4000 to Factory Settings
  • Changed RVS IP Adress to the one I use in my network
  • Nothing else changed
  • Speedtest => Full Download Speed!
  • Step by Step configuration changes I usually do

I didn't believe it but the problem is the daylight savings time (automatic change)!

If I enable the "Auto Daylight Saving" feature the speed drops about 50%.

If I disable it, speed is at 100%

Best thing: The IPS Feature is still enabled!

I have no idea what this setting has to to with the connection speed, maybe someone from Cisco can help here?

I will retry speedtests the next days to check if the full speed is still available.

Here a screenshot of the setting (100% speed).

I did some additional testing with other configuration settings. It seems that at leats some of the settings lead to the same effect. Setting changed => slow internet. Reboot RVS400 => speed ok again.

Second thing: after two days without any configuration change speed falls also down again. Reboot of RVS4000 => speed ok again.

So at the moment I think the setting itself is not the real problem because the "slow" speed comes back after some time.

I think I will sent the RVS4000 back and buy another router. Not only because of the speed, it also doesn't support VPN with iOS (iPAD) devices.
