Hi,
I've just bought an E4200 and I've just installed dd-wrt.
I see there is an official thread here http://www.dd-wrt.com/phpBB2/viewtopic.php?t=86316&postdays=0&postorder=asc&start=690 but it is locked!
Where is the actual official one?
I'd like to troubleshoot a problem with wol: ip neigh command seems not "accepted"...
---edit---
Edited up here, problem with WiFi is just solved.

I've just read about the v2 and I'm already quite angry because seems v2 offers real 3x3mimo on both interfaces. I would like to understand if I'm having a v2, even if I'm quite sure it's not....how to do it!?
Dd-wrt indicates 300+450 mbps, so I think it's a v1...

Guys, well, I'm trying any other WiFi settings and I can't understand how I can't seem to get 300mbps with an Intel 5100 AGN card and why a 2.4ghz smartphone seems to like the 5ghz radio the most, and all the speeds become baad
How should I set 1st and 2nd interfaces? I've given them the same name and protection (wpa2 aes). But what about modes, frame burst =on on both, afterburner(s)=off(2.4ghz) and auto(5ghz), channels and widths?
I used to use "auto" everywhere but doing so all my devices are capped at 54mbps. And I'm sooo confused because it seems like the 2nd 5ghz radio can do 2.4 too
I would like my smartphone to use the 2.4ghz only radio and go @64/72 as it does with the 5ghz one, and the pc use the 2+5ghz radio at 5 only. Instead it doesn't see it as a 5 network if I don't set it at 5 only on dd-wrt. I also set a preference on 5ghz in the Intel 5100 settings but there's no way to go @5ghz even setting NA only in dd-wrt. It does 2.4, slowly (48/54) while it should get 300mbps anyway.

In short, what's the best settings having a 802.11n 2.4ghz (max 72mbps) and a 802.11agn 2+5ghz card (max 300mbps)?

An easy work-around for this would be to set the SSID's on the radios different, give each a unique SSID and then whichever device you want to connect to what, do so. Then config your device to always (preferably) connect to that SSID.

I've tried that too, and it avoids the smartphone to connect to the 5 radio.
But I still get max 120mbps with the Intel 5100agn card anyway I set it, sometimes I see 300mbps for a bunch of seconds just after connection but it's not maintained at all.
I've just reverted to "mixed" everywhere and I now see something weird:
1.smartphone connected to wl1(2+5ghz) radio at 72mbps @ 2.4ghz
2.intel 5100agn connected to wl1(2+5ghz) radio at 121mbps
DD-wrt shows max 54mbps for wl1 and max 52mbps for the wl0 radio!?
Nothing matches so...where's the truth!? Is it some sort of bug of dd-wrt?

And your channel width is set on 40Mhz? Also its best to set your channels manually, and not let it auto, refer to the Wireless N Conf link in my sig for more info.

That's exactly the wiki I was reading again and again
Well, I tried doing this way:
wl0: all auto, smartphone connected at 72mbps. It's ok, status page reports right speed too.
wl1:N Only 5ghz, channel 132 ( I see 162 is the recommended one but not permitted in EU as far as I understood), 40mhz, lower control channel.
Here we are, Intel 5100 AGN is connected at 300Mbps, but keeps sending packets and receiving nothing. DD-wrt page still shows max 450mbps and that mac as connected. But I still have 0 packets received. I was trying the transfer of large files from/to that pc from wired sources and I couldn't go after 9-10MB/s before, when it indicated 100/160mbps.
---edit---
It was a "lock" of the network card itself, because after having rebooted the router the situation was the same, after having disabled and re enabled the network card of the notebook it reconnected and exchanged data, again at 80/160Mbps max...
I have just updated its drivers to the latest Intel release so I am still excluding it as the culprit of the slowness!
I still see sometimes it goes to 300Mbps but network usage goes to 0% (no data exchanged) so there must be something else, because it seems to try to use them all but just can't for other reasons...
---edit1---
I've tried every settings for both the router and the network card seen here http://www.dd-wrt.com/phpBB2/viewtopic.php?t=145519&highlight=intel+5100 where users got 300Mbps.
I am still not getting them, max 160Mbps. Perhaps it's a bug of the dd-wrt version I'm using DD-WRT v24-sp2 (11/29/11) mega - build 17949.
---edit2---
Seems stupid, I am doing tests from within a room just 4-5m away from the router, signal is "Excellent" and there is open space between the notebook and the router. Going far the router doesn't help (max 160Mbps) but going 2-3m away from it let me reach 220/240Mbps. Is this normal, 2m in LOS almost doubles the rate?

Difference between E4200 v1 and v2 is, v2 is N900 compliant, and the data rate on both channels is increased to 450.
