Hello!

No I've connected the iPad to 5Ghz and now it works loke a charm.
I'll try to make such a dump to help you with a possible troubleshoot.

BTW: The iPad is a really magical device.

My wireless wouldn't come up the first time either, I had to enable them first. (By the way, settings the channel on "auto" breaks the whole thing, the network will show up as "disabled or not associated" (or something like that).

From my experience, boosting the signal a couple of dbm can make the difference, right now I'm struggling to get a stable connection on my laptop, two concrete floors and a wall or two away. I can't place my laptop on my amp, or I'll lose connection. It also helps with the samba transfer speeds when the network is the bottleneck (like right now).

The maximum right now on the 2.4GHz band is 20dBm, or 100mW, and 17dBm (50mw) on the 5Ghz band. My reg domain right now is Canada. With dd-wrt I used to be able to get 26dBm + 3 gain on both bands, until they broke it (after which I could only get 21 tops on the 5GHz band).

Iphone 4 has the same issue.

I am really curious about how to get teh 27dbm... XD after seeing this:

I'm using an iPhone 3GS works just fine.

I am also having the same build 26041, maybe i should update, but i was having less performance with the newer builds, its not a fair trade XD

Is there an easy way of getting single link mlppp working with this firmware?

Also regarding the firewall, by default when I test any ports using shields up! at www.grc.com they all show as Closed (aka Failed test) instead of Stealth. In contrast to my WRT54G running Tomato firmware whos ports would always show as Stealth until I opened them under port forwarding. Can you explain why this is? Furthermore im unable to actually open any port, regardless of how I specify the rules. They seem clear enough to me (source wan, protocol TCP+UDP, device IP (which is static) and port, set to Accept) and yet it doesnt work.

Please read this to learn why "stealth ports" are not actually making your host stealth at all: http://www.wilderssecurity.com/showthread.php?t=216892
Afterwards you can still achieve that by changing the policy from reject to drop and by optionally removing the standard icmp allow rule.

does anybody know how to get the 27dbm? I tried yesterday to do iw reg set US and change both networks to US and it was still limited to 20dbm...

I found that screen on an italian wndr3700 forum

@abolition

Apparently it's a hardware issue: https://forum.openwrt.org/viewtopic.php?id=26285

Do you know for sure the router in the screenshot was a 3700? Could anybody with a V2 comment whether or not they can change power levels with a regdomain that allows it?

his builds never goes up to 27dbm,so forget about it~~it seems like my build~~~

That's very informative, thank you for that..

EDIT: http://www.hwupgrade.it/forum/showpost. … count=4775

They're saying to change country to somewhere in North America to allow higher power levels. As mentioned in the previously linked thread, that doesn't work. Even setting "00" (world) will not allow this. They're using coatto87's build from what I can tell.

Thats interesting information you found, what i dont know is how they managed to get 180mbit up and 160 mbit down...

It seems they added some more patches 1 hour ago, waiting for your build to test (26284)

testing with the latest build 26281

Very bad Rx rate, I dont know how to improve it

Ok ill look into this. As for MLPPP, any way of enabling single line multi link?

@abolition

A new build is compiling right now to enable the default SSID 'OpenWrt' again, but don't expect a small fix like 26284 to improve your performance. Are you using 40MHz? Any other devices nearby using the same channels?

I am using 40MHZ in both 2.4 and 5ghz, the mac is limited on 2.4 to 20MHZ so i kind of ignore 2.4, with 26041 however i could achieve at least 2more mb both ways.

What I am worried about is with 5ghz, I am alone in my neighborhood I tried with all the channels and this does not improve. I am about 2 meters from the router and at the same height I am holding the laptop. Why do I get such nice speeds on upload but so bad on download?

I don't know, because the ath9k performance suck? Are others getting higher speeds? Did you try a different N client?

My windows machines never get more than 8MB/s (on the mac I get about 11MB/s down).

I thought it could be my macbook but I did some tests in the office with our wireless equipment (ruckus something) and I was getting 23MB/s up 18 MB/s down on 5ghz same channel.

The only con is that that wireless ap costs 400e a piece XD

What kind of driver does the original netgear firmware use? Isnt it based on openwrt?

I just upgraded to r26281 and encountered what I would like to spare others:
- sysupgrade failed: I had to TFTP after reset (can be ovecome...)
- Restoring backup with Luci just failed. Remained at factory defaults. (untarred manually)
- Luci shows no information at all (bandwith, leeases, interfaces, all remains "collecting data"

I don't know the cause, but my advice: skip this release.

---> UPDATE: just checked Firefox. some caching problem: pages didn't refresh properly

I did sysupgrade without a problem and all my settings remained untouched. regards.

Just did a sysupgrade to R26284 without problems. All settings were still there.

Sysupgrades are always a risk. My advice is to stop every service on the router and unmount external storage before you upgrade.

Here's what I do:

#!/bin/sh
nzbget -Q
/etc/init.d/minidlna stop
/etc/init.d/miniupnpd stop
/etc/init.d/pptpd stop
/etc/init.d/nfsd stop
/etc/init.d/portmap stop
/etc/init.d/avahi-daemon stop
/etc/init.d/pure-ftpd stop
/etc/init.d/samba stop
/etc/init.d/uhttpd stop
/etc/init.d/hd-idle stop
/etc/init.d/cron stop
/etc/init.d/aiccu stop
/etc/init.d/radvd stop
killall ntpclient

Hasn't failed once after I started doing that. Upgraded to 26281 and 26284 without problems. And I backup /overlay myself, never trust a gui

So you backup you settings, but don't start fresh each time over? That's cool because I like keeping up with the latest release but get a bit tired of the long procedure to get back in business.

I also end up with a wireless factory-like settings router (so need to hook up cable etc.)

Hi
After unsuccessful try with latest Trunk Versions for WNDR3700V2, i tried your latest Build.
Unfortunately Multicast (ip tv) is also not working and stops after 10 secs.    Can somebody give me some advice?
Thanks
Primalair

@Teezee

Yeah I use sysupgrade. In case it fails I have my backup that I could just untar to /overlay after a factory flash.

I'm sorry, i'm forgot to read latest pages of this thread.

About wifi tx power, i have simply disabled regdomain.

I know it is a bad idea but the first time i tried OpenWrt, i noticed the poor coverage of wireless.
So, i thinked of disable regdomain to have more tx power and now the coverage is very good, specially with my Apple device (iPad 1G, iPhone 4 and Macbook).

Everybody knows that the use of channel and tx power different from country's rules is illegal, so i'm not responsable for any risks or troubles in law.

But i think the tx power of regdomain is too low, i know in the firmware stock the 2.4Ghz band has a tx power of 26dBm that is the value i can suggest.

bye
