**@Dmitry** - No problems, i knew very well what the risks were before flashing CC for the v2. I have sent the unit in for repairs this morning. The repair will either be free or paid, depending on the judgement of the service center, but i will have the 1043 back in a couple of weeks tops.


**@rotanid** - Again, i am not very versed with network products and Linux, but i work in sales/support for a very large company selling Enterprise HW&SW. I have thus become accustomed to look at a problem from all possible angles. I was just thinking how your test is missing one key element: PPPoE & PPPoEv6. My link to the ISP is done via PPPoE and PPPoEv6 and i gather the tests you've made did not involve PPPoE at all. If your connection is over PPPoE and you have at least a 300/150 line, try using the 1043 as your main router, connect a wired client to switch port 1 and do a speedtest run against a local server.

I state again that when i got this router i only had a 100 mbit line and it ran fine for a whole month. It's only when i upgraded to 300/150 that the issue became obvious.

One more thing to consider: i have a pretty solid laptop connected to the router via a wireless connection, 300/300 mbit (40 MHz channel). On this laptop i'd get ~150 mbit up and ~140 down on the speedtest site. The router has never crashed when the test was done via wireless; i must have done over 30 runs.

Hope this helps more than it adds confusion into the equation.

P.S. - I will perform the same test with iperf when i get the unit back from the service.
