Built for speed, the Simultaneous Dual-Band Wireless-N Router delivers double the bandwidth so you can enjoy movies, gaming and music more smoothly, with less lag, all around your home. Easy to use and set up; includes Mac setup wizard.
Experience faster wireless connectivity with fewer interruptions with two bands of Wireless-N, today's most advanced wireless technology. The 5 GHz and 2.4 GHz bands are designed to work separately yet simultaneously, so you can easily customize your ideal configuration - for example, use the 2.4 GHz band to surf, email and print while keeping the less crowded 5 GHz band free for time sensitive traffic like music, gaming and high-definition video.
Customer Reviews of Linksys WRT400N Simultaneous Dual-Band Wireless-N Router, Refurbished
Works like a champ11/2/2010
Once installed, this unit has been great. Surprisingly, the 2.4GHz band seems to be more robust (has more signal travel) than the 5.0GHz band, but that may simply be my environment. With other 2.4G devices (phones) in the area, no problem! There were some bumps in the setup process - specifically, the software was taking a long time to complete tasks which made me think it had gotten locked up. It did work itself out, though, and once installed, no further maintenance required. It's been running strong for a couple of weeks, zero complaints. I'm using an old laptop built-in WiFi(b), an older internal Apple Airport (again WiFi b), and a new LinkSys USB adaptor (WiFi n) on this network with WPA2. Plug and play. It's great.
Once again another refurb winner.10/26/2010
I'm not one to shy away from something because it's a refurb, and this buy is a good reason why.Out of the box it's been performing like a champ.My 2.4ghz band gets walked all over where I am,but this router is doing great on the 5ghz band AND is an improvement over my Netgear 2.4ghz router's coverage and speed.Streaming HD from one end of the house to the other was impossible before I got this and I only occasionally get an artifact here and there,and those could be from the video itself.The biggest issue I have is not being able to see who is on your network unless they are using DHCP,but this may just be in a place I haven't looked yet. If you buy a refurb and it's bad or going to turn out bad,you'll probably know it either immediately,or very soon.If it's from a reputable dealer,you return it,get a replacement or refund-chalk up one to the loss colum,and get something else.BUT if it does work fine,,you just got a great item for a great price.And it may be a refurb just because someone who didn't know what they were doing returned it,never had a problem.At this kind of savings,,I'll gamble a little.
The router I received is defective10/3/2010
I left a positive review soon after receiving my wireless router. I was especially impressed with how easy it was to set up using the included software. A few days later, however, I am fed up with it and am returning the router. It rarely broadcasts for more than thirty uninterrupted seconds, so I can open one webpage, but when I click a link, more likely than not, my speed drops to 0 MBPS, and the page won't open at all or will take several minutes. Forget watching a video clip; the connection always drops away within seconds. At exactly the same time the wireless is unresponsive, my computer on the wired ethernet will be surfing at full speed, no delays, so it is a router problem, not a network problem. The item was originally returned to the manufacturer because it had a problem; they apparently stuck a refurbished label on it and resold it to me at a discount. It still has a problem. I'm going to return it too, and they'll sell it to the next person looking for a bargain. I learned my lesson--I'm sending this one back and buying a new one of a different brand. I wanted a bargain and I got a low price, but that's all I got. It's utterly useless as a router. Just know you're taking a risk with a refurb. It might work, but it might not. Mine didn't.
Great router if you can get a good one8/30/2010
The wifi connection disconnected every once in a while. Even after upgrading the linksys firmware the problem didn't go away. Finally I installed DD-WRT firmware which did the trick. Now the signal is stronger and only disconnects very seldom. I love the router now.
Best 5Ghz Router for the price8/22/2010
I had been looking for a 5Ghz router for a while since I live in an apartment complex where the 2.4 Ghz bands are all overcrowded, and this router has performed amazingly given how little I had to spend. The dual radios are nice, since they allow legacy devices to connect as well. Unfortunately, this router was dropped during Linksys's transition from the WRT naming scheme to the eXXXX naming scheme, but this router is far superior to the current e2000 (former WRT320N) in wireless performance.
Worked like a charm.
