Thanks, I guess I should just follow the guide given on this site in Tutorials for Asus RT-N16 which means mainly to do that initial power reset (which can't hurt anything anyway) plus as you say the nvram reset after… (I have been flashing some ten WRT54-GLs with Tomato from Polarcloud to use as APs)
As for waiting, I would be buying the E4200 for family that I take care of network for them and I am soon about to move away and this is one of the last thing I can do for them, meaning I can't wait much plus this will be more than good enough for them (I want to switch them from 6 to 50 Mb internet and have to get new router).
I looked at Asus and at Linksys and Asus seems to be just plain plastic box plus it has those antenas sticking out and where I place it in the basment where network is located its role as WAP will be practically nill anyway (the house & property (ten normal housing lots) is very big and I have seven APs placed in various points around it). So I don't really care about wireless side of it and could do without it even, so the fact that Linksys has the antenas built in is a plus for me (even though I suspect the antenas on Asus likely do better job).
As for E3000 vs 4200. With $60 discount the price is the same as E3000 and so I thought why not go with 4200 then, if only because I think its case looks a bit more professional. Granted this is refurbished unit but I think that will be fine given it will work as it should to begin with (refurbs I think have somewhat higher chance to fail 'out of starting gate', that is you have higher likelyhood to have to make return upon purchase than with non-refurbished units).
Here I got a bit confused when looking at which firmware to choose for E4200. In Compatibility section here it says you should use special firmware like for E3000 but then in download section I see no E4200 special, and the E3000 download says 'Only for E3000'.
I wasn't sure if I should use the E3000 for my E4200 or just use the normal non-type specified kind just above. Then I read forum and found this thread and downloaded from that Toastmaster site…
Not sure yet if I should use the RT (safer version) or the RT-N (more on the cutting edge version). Both I talk about the latest builds. I downloaded the non-VLAN version, the VPN one as I might look into VPN whether I could make a go of that, setting it up.
Also looked at that NOCAT version - I am wondering if that could be used at home when friends bring their laptos to your place and you don't have to give out your house WPA password but they can log in with some guest password via that 'nocat' interface.
But I have no idea if that can be setup and used like that. Do you have opinion on that?
