D-link dir 879 a1

Hardware Questions and Recommendations
1

Hello, I recently discovered that I have an option to use this custom firmware instead of proprietary one. Unfortunately I have a very unusual router and its no longer supported(d-link dir 879 revision a1). I couldn't find the firmware for it on the list, but can I use the firmware from 878 revision a1 on my device or its a bad idea?

My router has this hardware - processor Realtek RTL8198C, 16 MB flash storage, 128 MB ram, gigabit ports 1xWAN+4xLAN, two radio blocks – Realtek RTL8194AR (2,4 gHz, 802.11b/g/n, up to 600 Mb/s) and Realtek RTL8814AR (5 gHz, 802.11a/n/ac, up to 1300 Mb/s)

I will appreciate any help.

it is a bad idea.

Thank you. I guess I was really unlucky with this model. But now I have supported list of routers so my next router will be a supported one.

RTL8198C has never been supported by OpenWrt (and isn't very likely to ever will be, search for 'lexra' about the details).

some say that RTL8198 is lexra, but RTL8198C is mips.
there are rtk sdk for 8198C and some people says it's code are crap that mixing some lexra code with mips24kc code. another 8198D is ramips. is it correct ?

RTL8198C is mips 1074Kc, correct - but that doesn't mean that OpenWrt would support the SOC automatically (so the reference to lexra applies to quite some extent, yes, it's mips and technically not lexra, no, there is little to no support); RTL8198C is mips 1074Kc as well (but clocked higher) , so the same applies there as well. Your challenge, should you accept it, would be developing basic SOC support, drivers for all the embedded IP cores (clocks, networking et al) and wireless drivers (which tend to be rather questionable).

ramips stands for RaLink (who have been bought by Mediatek), not Realtek - so very different.
