My problem is with my new DIR-825 with gargoyle 1.5.7 with identical settings as above attached to TG585v8 does not work, no internet access at all.
I also put gargoyle 1.4.7 on a WRT54GS with the TG585v8 with the same settings and no internet with that also.
So Im back using the TP-link successfully and cant work out why the other 2 routers wont work.
