WNDR3700v1 (US) 5ghz Channels Not Right

Post by not_awake7 »

I am having a problem accessing more than four 5ghz channels using Gargoyle 1.5.4. I am running a WNDR3700v1 router, bought and run in the US. However, it appears that Gargoyle is defaulting me to "World (00)" instead of US, and I cannot use any 5ghz channels over channel 48.

Note that with other firmwares (DD-WRT for one) I can access channels such as 165 but for whatever reason I cannot under Gargoyle (I prefer Gargoyle for stability and simplicity but need the higher channels for video streaming).

When I do a dmesg I am seeing this:

===================
cfg80211: Calling CRDA to update world regulatory domain
ar71xx: pll_reg 0xb8050014: 0x1099

ath: EEPROM regdomain: 0x60

===================

And due to the World (not US) choice I am seeing the following (notice that only the first four are usable):

Frequencies:
* 5180 MHz [36] (17.0 dBm)
* 5200 MHz [40] (17.0 dBm)
* 5220 MHz [44] (17.0 dBm)
* 5240 MHz [48] (17.0 dBm)
* 5260 MHz [52] (20.0 dBm) (passive scanning, no IBSS, radar detection)
* 5280 MHz [56] (20.0 dBm) (passive scanning, no IBSS, radar detection)
* 5300 MHz [60] (20.0 dBm) (passive scanning, no IBSS, radar detection)
* 5320 MHz [64] (20.0 dBm) (passive scanning, no IBSS, radar detection)
* 5500 MHz [100] (21.0 dBm) (passive scanning, no IBSS, radar detection)
* 5520 MHz [104] (24.0 dBm) (passive scanning, no IBSS, radar detection)
* 5540 MHz [108] (24.0 dBm) (passive scanning, no IBSS, radar detection)
* 5560 MHz [112] (24.0 dBm) (passive scanning, no IBSS, radar detection)
* 5580 MHz [116] (24.0 dBm) (passive scanning, no IBSS, radar detection)
* 5600 MHz [120] (24.0 dBm) (passive scanning, no IBSS, radar detection)
* 5620 MHz [124] (24.0 dBm) (passive scanning, no IBSS, radar detection)
* 5640 MHz [128] (24.0 dBm) (passive scanning, no IBSS, radar detection)
* 5660 MHz [132] (24.0 dBm) (passive scanning, no IBSS, radar detection)
* 5680 MHz [136] (24.0 dBm) (passive scanning, no IBSS, radar detection)
* 5700 MHz [140] (21.0 dBm) (passive scanning, no IBSS, radar detection)
* 5745 MHz [149] (24.0 dBm) (passive scanning, no IBSS)
* 5765 MHz [153] (24.0 dBm) (passive scanning, no IBSS)
* 5785 MHz [157] (24.0 dBm) (passive scanning, no IBSS)
* 5805 MHz [161] (24.0 dBm) (passive scanning, no IBSS)
* 5825 MHz [165] (24.0 dBm) (passive scanning, no IBSS)

According to http://en.wikipedia.org/wiki/List_of_WL ... 2Fj.2Fn.29 I should have the following channels available legally:

36, 40, 44, 48, 149, 153, 157, 161, 165

however I am only able to use 36, 40, 44, and 48.

Any thoughts on how to fix this short of doing my own compilation?

Did you ever get this worked out?

Actually never did get this resolved in Gargoyle. I've noticed that Gargoyle only allows my WNDR3700v1 to go up to channel 48 on 5mhz. At 48 and below the blue light stays on and flickers, and inSSIDer sees the network. If I set it to any channel above 48 the blue light comes on and off immediately, and the network is never available.

In DMESG I see that it is defaulting to World Domain even though I am in the US and using the -NA firmware (1.5.6 right now).

DDWRT and stock firmware are the only ones that appear to support the higher 5ghz channels right now (the only ones that reach down one level in my house), but DDWRT's current version is unstable and Netgear's dies every week or two.

If Gargoyle would have a functional 5ghz over channel 48 (i.e. not default to World domain for whatever reason) I'd probably stick with it. For now I am for stability but hope this gets resolved in a newer firmware release (maybe upstream in OpenWrt?)...

Just a quick followup - I did finally manage to get the 5ghz channels back, but I had to compile the source myself with the "CONFIG_ATH_USER_REGD=y" setting. Basically I followed DoesItMatter's instructions here: http://www.gargoyle-router.com/phpbb/vi ... =13&t=3231

I think I also did a "iw reg set US" in SSH, but didn't need to do it a second time after doing an upgrade with save settings...

Keep in mind, I'm in the US and simply trying to use the channels I'm legally allowed to in the US. For some reason the default builds don't allow me to (defaults to World (00) domain) even though I bought my WNDR3700v1 in the US. Go figure...

Do you mind sharing your build? having the exact same problem and 5ghz become way to weak to be viable.
