Hi Jonm,  have the exavt same issue with my WDR3600 V1.5.  can you explain how to apply the patch (and the 3rd  md5sums file)  -  also do you think the same patch can work on DD-WRT firmware (i have the same issue with DD-WRT) 

Thanks a lot

Hi eyaller,
Follow the HOWTO, but after cloning the source, in the root directory issue "git apply patchfile". You don't need the md5sums.

I doubt the patch would work on DD-WRT.

Thank you buddy. Sorry I am going to ask a newbie question... Say I am applying the openwrt version that is designed to load from the stock firmware wwebpage (file aprox 8 mb) router re boots and I have a working router with openwrt. How do I know apply this patch ?

Thanks again.

To make use of this patch, you need to build OpenWrt from source.
In the meantime feel free to test the patched image I provide here (updated to r39792).

Hi jonm, the folder on googledrive seems empty, can you please post the patch again. I have the same combination TC7200-Modem and TL-WDR4300 router. I made the changes from post 13. I compiled it, but it would be nice to have just a patch for future builds. Btw. are the changes in post 14 for disabling LPI on the WAN-Port? (if not what would be the WAN-port)
Thanks in advance.

committed a cleaned up version of the fix in r41577

Great to hear that. I see the fix disables EEE on all ports. Personally I don't really care, but in my case disabling the WAN port only fixed the issue.
