Cisco RV 120W VERY slow performance and being unreachable

Hello!

I have strange issues with my RV 120W, which I bought after the recommendations from a Cisco/Linksys pre-sales support. I'm using this unit for SOHO environment with two clients (computers) connected and a few mobile clients. Nothing special and nothing complex. I replaced my WRT610N router with this one on behalf of the VPN features, the RV 120W offers.

Before initial setup I upgraded firmware to it's latest (1.0.1.3).

The issues I'm having with this thing are:

- very slow WLAN performance. And I mean - very, very slow. After doing some analysis I'm having a drop from 10Mbit/s to a stable speed of only a few houndrets of kilos per second. Even less. An average, constant speed test show no more than 50-80 kB/s. And I have a 20/20Mbit link.

- very slow WAN - LAN performance. Although not as slow as WLAN, even LAN is somehow slow with an average throughput from WAN to LAN show no more than 15Mbit/s.

- WAN IP address - host cannot be reached. After setting up the router to be able to echo the PING and be remotely managed, I can achive both services JUST for about 20 seconds after the unit reboots. After those 20 seconds, remote management sessions are timed out and the host is unreachable. But If I reboot the router again, I get it to work again - for no more than 20 seconds.

As this is my first (more) professional router, I'm not really sure if I've got my VPN setup correctly. I cannot get it my VPN to work either and I can't tell if these issues are related.

Any help would be appriciated.

Thanks

Um... hello!? Anyone?

I will get nuts with this crappy box. I'm trying EVERYTHING I can imagine and no success.

WLAN performance is ridiculos and unstable.

On top of the issues mentioned before, I also get "page cannot be opened" errors like some other fellas were mentioning.

If there is no quick sollution to this, I will throw this unit out the window.

As I am reading through these forums, there are many unhappy users around and nothing seems to be correcting the issues.

Hey Juka,


Sorry your having issues with the rv120w.


I seen that you upgraded the firmware on the rv120w when you got it.  I always do a factory reset of the device when upgrading the firmware.  I will first backup my configs, factory reset the device, then reload the configs. 


Try that since you did do a firmware upgrade to see if the device speeds up for you.


The wireless issues you were describing, I would do a wireless scan using a wireless analysis software like INSSIDER or something like it, that way you can see the wireless channels that are being used and set your router manually to a channel that has no or the least congestion.


Try this and let us know what you get.

Hi and thank you for your interest!

I have to say I've already done that. I even did the 30/30/30 reset per some knowledge. No improvements.

Next thing about WLAN performance is that I am only sitting like 5m from the router. And there are no walls between.

I did the scan earlier and there is no heavy traffic. Even though, this is not my first WLAN on the same spot. Linksys' performes much better.


What I was able to acomplish in the mean time is the VPN connection. But this VPN connection only works like for a minute after reset (like I was saying before with the ping command). I can't explain, really. After reboot and aprox. 2 minutes unit is reachable (echo) via the internet and VPN can be established. After another minute or so, everyhing stops and become unreachable. Internet works on the LAN but with other random issues described earlier.

Yeah, what your experiencing is definately not working as designed for the product.


I would contact the small business support center in your area and get a troubleshooting ticket opend up with them.

Did you get any resolution?  I returned my first RV120W thinking it was a hardware issue.  My second one is acting the same way.  I can configure it while connected to a laptop with no internet connection.  As soon as I connect it to the internet, it starts acting poorly.

Once I get an IP address (Charter Cable - DHCP) the router starts behaving erratically.  I open a continuous ping session in one window and an Intenet session in another.  Shortly after I surf to any URL, the continuous ping stops getting replies - it seems the router reboots.

So, I do a hardware reset (you know the little button), and the same issues occur.

Yes, I have updated to the latest firmware (1.0.1.3).

I am trying to set this up at home, but I have a few customers who are waiting to hear how this device works.  Unfortunately, at this point, I can't even say it works at all.  It is a shame, the features set is very attractive.

No, I haven't resolved this one. But I can tell you what I did do; I've returned this piece of junk and exchanged it for a 861 model and assigned myself for the CCNA training. There are times in life you just have to switch to the next level. This frustration was enough for me. As for the Cisco RV120W; well, someone should burn the whole production line.

I just installed my new RV 120W last night and found big performance and reliability issues with the WAN connection.

After much stuffing around, I found that there was a handshaking issue between the WAN port on the Cisco and the old Motorola VDSL set top box.

I put in a switch between the two devices, and things started working again.  The switch indicated a 10Mb Half Duplex connection to the STB.

When I removed the switch and set the Cisco WAN port to 10 Half, I couldn't get a link up. The only time the WAN port would link was if it was set to Auto. But then it was slow and unreliable.

So the switch has gone back in for a workaround.

I see in the release notes for Firmware 1.0.1.3 there is an open issue:

Issue—Interoperability issue with Intel VM version cards. For example, LNE110TX fails to connect when the duplex mode on the switch is changed to half-duplex mode.

Workaround—None.
