Re: [OpenWrt-Devel] Is this router openwrt compatible?

[Gioacchino Mazzurco]

ok very thanks ;) we cannot at all because we use openwrt full of ipv6 stuff
then it is impossible to run on a 2MB flash :|

According to the FCC photos, this thing is a AR2317 with 8 MByte ram.
While the flash chip isn't visible in the photos, it most likely is a
2 MByte one, which makes it all in all definitely not supported by
stock openwrt. Even getting a custom stripped down version to run
might be near impossible (and no fun).

[OpenWrt-Devel] Is this router openwrt compatible?

[Gioacchino Mazzurco]

Hey all!
I see this big promotion on axuse.com site
http://www.axuse.com/produkt/AX10447/Router_TLWR340G_TPLink/448/24/001001004/en/

I am looking for if it is compatible with openwrt, and if it support
multiple Acces Point with one radio ( like fonera and other madwifi )

because we can use this low price router, in place where we risk node steal

some one know?

[OpenWrt-Devel] [PATCH] 3G modem - don't require a pincode

[Jose Vasconcellos]

Some ISPs don't use a pincode on their SIM cards.
This patch checks to see if a pincode is defined before
trying to set it.

Re: [OpenWrt-Devel] [PATCH 4/4 v2] package/mac80211 refactor ath9k_platform to support ath5k

[Daniel Golle]

Ouch, ath_platform_data.eeprom_data isn't a pointer actually :/
As one might well supply a MAC address only, it would make sense to make 
it one.

Otherwise I will change pdata->eeprom_data to pdata.eeprom_data ...


On 06/24/2010 07:28 PM, daniel.go...@gmail.com wrote:

This adds a patch to mac80211 which modifies the ath5k driver in such a way 
that it respects eeprom_data and mac from ath_platform_data.
If ath_platform_data is supplied, ath_platform_data->eeprom_data is used 
instead of reading from the module eeprom.
Similarly, a non-zero macaddr given in ath_platform_data overrides the mac 
address.

[OpenWrt-Devel] [PATCH] package/madwifi override MAC address from platform_data

[daniel . golle]

This patch makes ath_pci check for ath_platform_data and set the MAC address to 
the one provided in ath_platform_data.
It's built upon the changes in my previous posts related to 
refactoring/renaming ath9k_platform_data.

be done in dirty ways.
However, overriding the interface address is possible with a small modification 
of if_ath.c, which appears to be covered by the GPL.

(I believe, a patch-of-a-patch would by even less convenient than attaching the 
file to be put into package/madwifi/patches)
