802.11n mode on Linksys E4200 v1


I am trying to repurpose an old Linksys E4200 v1 as an access point.
The problem is that wireless 'n' mode is not available on either radio0 or radio1, only '802.11bg'.
Issue is present on openwrt 18.06.8 & 19.07.3

I have tried changing the country code to 00 - world, driver default, GB and US and given the device a reboot after each change, I have also confirmed g speeds by running a speedtest and I am being capped at around 24Mbps which is near enough max for g networks. I'm not realy sure where to look now.


Your chip might very well only offer 802.11g with the FOSS b43 driver.

The binary blob (wl?) might do 802.11n, but I don't know if OpenWrt offers one that works with the newer kernels OpenWrt uses.

BCM4718A1 is only supported by b43, but b43 doesn't have any kind of support for HT modes, which would be required for achieving throughputs above 54 MBit/s (and no, there is no hope for this to change in the future). If you need more performance, you'll have to look for a better supported router (there are quite a few nice devices on the used market for rather little money).


I have the E3200, similar to the E4200, and I have loaded freshtomato on it. 802.11n beyond 54Mbps works.


You can find code for the E4200 at


The freshtomato code has support for the USB 5Ghz radio on the E3200, but performance is limited. On mine, I get about 81Mbps on the 5Ghz and CPU is at 99% usage (known issue).

I think tomato is the only firmware that supports the USB 5Ghz radio. It's not on dd-wrt and openwrt.

AFAIK, pedro is actively maintaining the code as he has already released 5 versions in 2020. Most of the maintenance is in updating all the busybox components.


PS. I have downloaded and built freshtomato firmware myself and it works.

dd-wrt has a build for the E4200v1. See


AFAIK, dd-wrt has some $$$ arrangement with broadcom to use their closed sourced drivers. I have no idea, though, whether those drivers ever get updated by broadcom or not.

Thanks all for your help on this one.

@retiredtab everytime i see of hear “dd wrt” i get this cold shiver and feeling of uneasiness :rofl:

I may give freshtomato a shot, its been a while since i checked the tomato scene
