Hi there!

I recently purchased a Linksys WRT300N v2.0 802.11n wireless router which I am have a problem with.

I have several computers around the house.  2 of these have 802.11n, 2 of them have 802.11g.  The router is running in mixed mode, meaning it should (in theory) operate successfully with all devices...

I am able to connect with my 802.11g devices and maintain a steady 54Mbps connection on them.  I am able to connect with my 802.11n devices and maintain a connection - however this fluctuates between 1Mbps and 170Mbps, occasionally up to 200Mbps.  This fluctuation happens several times a minute, maybe 20 or so?

In practical terms the problem manifests itself by my not being able to maintain a connection to network shares.  If i access my media center in the lounge for instance (which has 802.11n) from my iMac in the office (802.11n), and try to access a shared folder - then move content from the office to the lounge...my connection is maintained for 5-10 seconds and then drops out.  However, if i stick a usb 802.11g adapter in the media center and access the share from my laptop for example (802.11g) i can maintain a great stable connection up to 54Mbps.  Something that bothers me is that in the router config screen under the "Mode" option, I only have the option to select Mixed or Disable.  I chose disable thinking it might just default to 802.11n but nope, cut my wireless completely.  So thats not an option i think :)

So, i'm thinking the router is okay, but there are some settings I am missing that enable it to run smoothly in mixed mode.  I have taken the 802.11g devices out of the loop and just tried using the 802.11n devices on the network - but the same thing happens and i can't maintain a stable connection.

The weird thing is i can use the internet at full speed on ALL devices at once - there are no internet dropouts.  This problem seems isolated to my internal network!  Oh, and i've tried just using a wired network and that works fine as well.

The firmware on the router is 2.00.08  I've been trying to track down info as to whether this needs to be updated but i'm hitting walls. 

Does ANYONE out there have this router?  Had any issues with it on a mixed mode network?  Had and joy fixing those issues?  I would love to get this sorted instead of bring back the router as I really think its a configuration issue not a hardware issue.

Cheers all

Mike
