Is this an older PC with an old network card ...if so check to see if it network card needs a new driver. Or if you are lucky maybe its just a bad Ethernet cable between your PC and router?

BTW, are you able to connect the PC using wireless?

I was getting the same problem with the V1, even with DD-WRT firmware. So I really wonder what is my issue...

For information, I got an Iomega network drive on the network as well, but even if I unplugged it, it doesn't fix the issue.

Any ideas ?

Thanks in advance!

Try turning off UPNP in the router - the factory firmware is bugged there, and causes problems like you've observed - since DD-WRT is based off the old WRT54G, it inherited that bug.

Well, that's quite strange. I switched back to Wifi and now, my internet speed is alright, 2mb/sec like normal. But then, Youtube videos don't stream anymore... I thought it was something else and after several attemps to fix this, I decided to switch back to Ethernet. Now, youtube videos are working back again, but my speed is inconsistant..

I got two theories;

1. When I install the last version of Adobe Flash Player, I was probably in wired mode.
2. My router wired connection OR my motherboard ethernet connection got an issue.

I tried several ethernet cables and it doesn't change a thing. UPNP is disabled btw.

Any ideas?

New firmware update out for e4200 V2: 2.0.37.131676 and update to Cisco Connect Express on iOS from ver 1.1 to 1.2

I haven't been able to find any details posted for the V2's firmware yet.


Cisco Connect "express" app 1.2 update includes::
Added support for EA2700, EA3500, EA4500 and E4200 V2
French Language support
Changed short name to "Express"
Fixed a problem when canceling from adding a device to via WPS

I just confirmed ( after reading comments in Cisco's Home Community forum) that the new V2 firmware 2.0.37.131676 includes the WPS fix. Once updated you have to go back into the Wireless/Wireless Settings/menu and select or reselect the Wi-fi Protected Setup. Then you will see the additional menu items to include new features to enable or disable WPS.

Configuration View ( Under Wireless/Wireless Settings)

Manual Wi-Fi Protected Setup™
WPS: Enable Disable

Looks like Cisco pulled 2.0.37 yesterday. Something must have been wrong with the firmware. Back to 2.0.36 for now

Firmware 2.0.37 with WPS security fix is back! Hopefully it will stay put for a bit longer this time
