They are on Sky Fibre (40mb/2mb). Sky Fibre Pro is 80mb/20mb
True, but its also because we all ordered before they soft launched the pro service, hence we actually have installs, and not dates at the end of this month.
Is the tomato firmware better than default, mine seems pretty unstable on 2.4GHz though I'm in a very busy wifi area (30-40 AP's in range)
Sorry I meant is the tomato firmware better than the cisco default excluding the option 61 part as I'll leave sky's router just doing the connection and WAN and 4200 elsewhere doing LAN / wifi.
Tomato has surprised me a lot. It's got some great tweaks in it (like being able to Name my MAC Wifi list items) and real time bandwidth graphs, but yes its super stable.
My Router has been super stable since day 1 though both 2.4GHz and 5GHz, and I am glad I went with this router due to the 610N before being so bad (resets almost every day, power cycles mandatory at least 2 times a week, 5GHz DID NOT WORK just causing self reset loops). Almost put me off Linksys entirely.
Anyway back to the point. Its stable, but if you have 2.4GHz problems now I wouldn't expect them to go away. Also the only firmware out is for v1 E4200s, so if you have a v2 you might be in for a wait, which might not even end.
I used the Toastman build
LINK and it pulled all my settings from my router automatically which I didnt expect.
I said I had DNS issues before and that might be because I had a alternate DNS set in the router, so it might be worth resetting your settings before you try (make a back-up on your default OS first just in case you go back). I havent bothered retrying yet I'm leaving it to settle past the DLM period first before I have another go, but I am sure that will be my issue since Chrome was throwing a DNS error.
In all honesty you may aswell try it, its easy to do (just install it like any FW update) and just as easy to go back. The only problem would be from a bad flash possibly.
Still getting between 37 and 38Mbps too. My Phone (One X) gets 25Mbps over WiFi and my iPad about 31-32Mbps.
