40Mhz impossible? (TP-Link 1043 V2.1)

[Lessram]

For over a week I am strugling with this firmware combined with a TP-Link 1043.

To tell the short version:
hardware: TP-Link 1043 V2.1 with Gargoyle 1.6
Internet connection: 150 Mb/s down, 10 Mb/s up
Wifi-N card: Ralink 3090 (150 Mbps)

To exclude all interference:
Placed router next to laptop connected with a CAT5 UTP cable
I excluded all other MAC adresses besides my own laptop

Problem:
Can NOT get Wifi to 40Mhz
Tried channel 1, 6 and 11 plus 2 above/below
Highest download speed 35Mbps (Speedtest.net)

Now....after 7 days of trial&error.... I don't know anymore.
It already costed me my previous router (TP-Link 1043 V1) which got bricked during a flash some days ago.
Someone???

See that thread and read through the whole thing

That will help you enable 40 Mhz

[Lessram]

Thank you, but would enabling Channel 12 & 13 make 40Mhz possible? It's not that crowdy with WiFi signals here.

These Linux codes hacks look like abracadabra to me
Don't even see a way to include those hacks.
All I see is the option to add plugins through URL

Yep it's all tied together.

That reghack will allow 40 mhz, all the other channels, etc.

One step forward....

Installed: Webshell

and used this;

Code: Select all

cd /tmp/
wget http://luci.subsignal.org/~jow/reghack/reghack.mips.elf
chmod +x reghack.mips.elf
./reghack.mips.elf /lib/modules/*/ath.ko
./reghack.mips.elf /lib/modules/*/cfg80211.ko
reboot

This worked on Gargoyle-ispy 2014-February-16

So.... thinking I found the solution, I upgraded again to Gargoyle 1.6.0 and did the same trick.
Result.... Channel 12 and 13 show up. But 40Mhz does not... not even with and 2nd channel below (Tried multiple channels)

Help?

Even though INSSIDER tells me I have a 450Mbps Max rate, it still just works at 20Mhz. Might this be a solution?

from: http://wiki.openwrt.org/doc/uci/wireless

40 MHz channel (300 Mbps)
Stuck at 130Mbps? Get 300Mbps! Note: this violates regulatory requirements.
Edit the file /etc/config/wireless, and restart the wifi AP by executing the following commands…

Code: Select all

  uci set wireless.radio0.htmode=HT40+  # or: HT40- if using channel 11
  uci set wireless.radio0.noscan=1
  uci commit wireless; wifi

Note that option 'htmode' should be set to either HT40+ (for channels 1-7) or HT40- (for channels 5-11). You have to use WPA2 encryption with AES.

Right, you have to do the reghack thing I posted.

Reason is, when Eric and OpenWRT compile images, they have to
abide by the regulatory requirements.

If you want to go around those, it's your call/responsibility.

I compile my own OpenWRT trunk versions and in compile options,
I have it ignore any of those, so I have full channels and full 40mhz

[Lessram]

I feel so stupid. I am reading the entire thread over and over, following links-to-links-to-links but don't know which specific hack you mean.
Maybe you explained it in this post:
http://www.gargoyle-router.com/phpbb/vi ... 231#p14641

But I don't see exactly how I can "make it myself"

So I used both codes mentioned earlier;
(Executing line by line in WebShell)

Code: Select all

 
cd /tmp/
wget http://luci.subsignal.org/~jow/reghack/reghack.mips.elf
chmod +x reghack.mips.elf
./reghack.mips.elf /lib/modules/*/ath.ko
./reghack.mips.elf /lib/modules/*/cfg80211.ko
reboot

and

40 MHz channel (300 Mbps)
Stuck at 130Mbps? Get 300Mbps! Note: this violates regulatory requirements.
Edit the file /etc/config/wireless, and restart the wifi AP by executing the following commands…

Code: Select all

uci set wireless.radio0.htmode=HT40+  # or: HT40- if using channel 11
uci set wireless.radio0.noscan=1
uci commit wireless; wifi

Note that option 'htmode' should be set to either HT40+ (for channels 1-7) or HT40- (for channels 5-11). You have to use WPA2 encryption with AES.

It seems to do the trick.
