    Hi all, I just bought a brand new Asus RT-N16, and I have Tomato RAF 1.28.8656 running on it. Seems to be running wonderfully so far, but I have noticed one thing. Not sure if it's a bug, or something else. All I know is my older WRT54G-TM with Tomato RAF did not have this issue.

    The issue is that whenever my Windows 7 PC (which is connected via wired ethernet, not wireless) resumes from a standby state, it takes 8-10 seconds to re-establish a connection to the router. In the windows taskbar I see a red X on the networking icon for 8-10 seconds. With my older WRT router, this didn't happen. The connection would be restored instantly and I'd never see that red X.

    Is there a setting I'm missing or is this just a normal occurance on the RT-N16?

    Sorry guys, I figured out the problem. The ethernet cable running between my PC and the router had only 2 pairs of wires in it, not 4. There was only a 100Base-TX connection being made, even though the router and my PC are both Gigabit. I swapped the cable out for a proper spec'd Cat5e cable, and not only did I connect at 1000Base now, but no more red X when I resume from standby.

    I guess the router and my nic were trying to establish a 1000base connection before, but couldn't, because the old cable was only 2 pair, which is why it took the extra few seconds to figure out that it couldn't do 1gbps with that cable.

    Substandard CAT5E cable

    This seems to be a good opportunity to remind posters that a lot of the CAT5E cable on the market is fake and/or faulty. The first 2 pairs used for 100Mbps are usually OK and to specification, but the second 4 (for 1000Mbps) are often around 3 or 4 times the resistance and will only do short cable runs. In Asia, AMP brand cable is, more often than not, of this kind - but the box looks genuine. Vendors will often charge a premium for cable that works! LINK cable has usually been fine.

    This is good advice. I also notice that websites load/render faster with a good cable as well. For those of you with a router that has a gigabit switch, and your wired PC is also gigabit, DEFINITELY check the ethernet cable. I didn't realize how much a good cat5 cable can make a difference compared to a bad one. I was using the bad one for YEARS on my old WRT54G-TM, but probably didn't notice anything because it is only 10/100.
