This is the worst router I've ever bought. This is my review for Amazon.
Hello, I never review anything I buy, ever. But this router has to be the worst piece of junk that I have ever bought. I honestly feel scammed, that's right SCAMMED. Wireless signal drops out frequently, by frequently I mean every 10 minutes or so. Packets are dropped at a rate of 20% or more. This so-called product, is an embarrasment for a company like Cisco to be selling. Please don't waste you money, or don't say I didn't warn you. If you feel like getting a second opinion just Google "e4200 dropped packets" and read for yourself. Oh and by the way, this is the 2nd e4200 router I've bought, because I thought my fist one was a dud (bought in Best Buy). What are the chances of getting 2 bad routers from different suppliers.... either 10000:1 or they are all plain broken. J
This certainly is not as good as advertised. I have dropped signals too, and had expected that with its supposedly superior range that would be a thing of the past. This thing worked well for two weeks then deteriorated. Cisco customer support is of absolutely no help; they will just advise you to try fixes without really explaining why they should work (which they didn't).
It's odd that some customers can get such great performance out of this thing while others find the experience poor.
Is your E4200 a hardware version 1 or 2? Have you tried to change the wireless channels on the router? If you're trying to connect to the 2.4 ghz band you can try channels 1,3,6,9, or 11. There are external factors that we have to consider when it comes to wireless connectivity: distance and interference with other wireless devices.
If you have tried those, you can try to update the firmware of the router which you can find from Cisco's homesupport site (http://homesupport.cisco.com/en-us/support/routers/E4200).
