Experiencing Packet Loss connecting to VPN - Wow says it the router?

Hi All,
I have a Netgear WGR614 G Wireless Router after the cable model. Then I have my laptop connected with a cat5 cable though.
The other main computer is connected wirelessly. Cruising the internet is not a problem, though WOW said I may not notice packet loss using the internet.

When I connected to my companies VPN I lose connections after a couple of minutes and then it reconnects.

Wide Open West says there is massive packet loss, so I said how do I fix that?
Not being too technical myself I hoped for an answer.

The CSR says call Netgear!!! What a lost cause that would be.

So simple question, do you think it is the router? Would upgrading the firmware help? Or should I buy a new one? Which brand is better?

These router are not business quality I guess for $70 - $100?
Would a business version be a better investment?

Any help would be appreciated.

Thanks
JJ

connect to your modem and see how it goes. if everything is OK through the modem try a firmware upgrade on your router. if it's still a problem think about another router

i have a normal linksys i bought years ago and it's OK. but the original firmware from years ago did have VPN issues

could also be your company's VPN. we used to have a Cisco PIX firewall and the Cisco VPN was horrible. Checkpoint is a lot better. or your company may have a policy of automatically disconnecting you after a few minutes of no activity

Thanks Al,

I'll definately give that a go, and download the latest firmware.
At work we use a Sonicwall Firewall and I am connecting using a Sonicwall vpn client program.

May also put a switch between the cable modem and wireless router and connect to the switch via cat5 cable.

Thanks again
JJ

Open up a command-line window and run tracert [name of your company's server]. That'll show you who's to blame.

That might not work, as some cable modems will only assign an IP address to one device at a time, and your router already's taking that.

You do have the right idea in taking the router out of the equation and testing though.

Which computer are you trying to connect with? Is it dropping packets on only the wifi connection, or on the LAN connection to the router as well?

I am using my company laptop on the LAN, not wireless. I had the exact same problem with the VPN on wireless though.

The IT admin said VPN doesnt work over wireless, but I had no issues really, apart from this packet loss issue!

Going to remove the wireless router from the network and try what you guys mentioned.

Thanks for the help.

That depends on how the wireless is setup, somtimes some of our users have problems with 40 bit encryption while 128 bit and everything else seems to work fine.

Sadly, more and more equipment is being configured to reject ICMP packets, making this old and valued tool less helpful.

I'm on the "test without router in the loop"/"upgrade router firmware" bandwagon.

Looks like all of your help has resolved the problem for now. I upgraded the wireless router from the initial 1.3 version - which came with the router to 1.9 from the netgear website.

Now I can use my VPN and the connection issue seems to have been resolved!!!!

Also using the VPN wirelessly worked for now.

I will monitor this from now on, but thanks for the help.
