Summary: I got this to replace my Linksys WRT54G wireless router. Loaded the CD, followed the prompts, did the router firmware flash upgrade and presto! Had to do some minor configuring on the laptop, but once that was done, the router works very well all over the house. I've had a couple of "drop-outs" from about 70-100 feet away but for the most part looks like this one may be a "keeper".
Summary: Overall, I wanted to investigate looking into a Wireless-N router that was not only cheap, but could be flashed with linux firmware and enhance its potential. Standard linksys firmware by all means, sucks. It is buggy, drops signals, and I've always as long as I can remember, had to reboot the thing once every couple weeks to a month, which would only occur more as the routers got older.
Summary: The router is as good as any other router I've had. This one didn't come with any manuals (don't know why), but instead had a CD with a setup program which was supposed to help you set up the router. The wizard was worthless. It gave no options for advanced settings unless you successfully configured with the wizard, which didn't work in my case because I have a VOIP router in line before this router.
Summary: Initially the WRT150N was great, Installation was a breeze. I then found out that when using with my laptop at home, it would drop the wireless connection for no reason. Evidently this has occured to many people. See the Linksys user form on problems with the WRT150N.
Summary: I was replacing my existing Linksys G router with an N router, and since I was happy with my old Linksys, I thought why not try a new Linksys. I received it and setup was very easy - it is indeed smaller than my old G version. Everything works wonderfully except for one little problem - I am currently unable to get it to transmit at full "N" speed. I went back and read through the manual and it actually indicates that it's transmission speed is "only" 54Mbps.
Summary: This is not my first wifi router, and I bought it to replace a flakey, four year old D-link unit that needed to be reset several times a day. So far after about a year's use, I haven't had any problems with either PCs or Macs on my home network. The complaints about "not working with Macs" are probably due to the user's lack of knowledge, not a problem with the router.
