Overall, I'm happy with this Chromebook after using it for four days. The only problem is that the wifi connection has been getting worse and worse.
The Chromebook keeps dropping wifi signals. To troubleshoot the problem, I've connected with my laptop side by side with my Chromebook and the laptop has no connection problems with the same network. The Chromebook shows the wifi signal at around 48% when the laptop shows 100%. I disconnected wifi on my laptop in case there was some kind of interference and tried again with the Chromebook, but that didn't help. This Chromebook problem started a couple of days after I started using it and seems to be getting worse.
Web surfing is still possible on the Chromebook because the disconnections are sporadic. The main problem is that my VPN disconnects every time the signal strength drops. Again, my laptop has no problems with the same network, the same VPN (and the same VPN server) and the same location. Do I have a bad unit?

So after many hours of testing...I have found a solution.
In fact, it does turn out to be a router setting for me.
I have a Cisco DPC3825 and I had to uncheck IP FLOOD DETECTION in the security tab.
Simple as that. My router log said that the Chromebook was sending LAN UDP Flood packets.
I apologize to ACER Tech Support.
It might be usefull to add a FAQ to this effect.

Can you try with other wifi net?
If yes, please repeat the same test (solderedbook and laptop) to check if the loss of signal is the same or something change.

I just used the Chromebook on public wifi for the first time. I was a place where my laptop had always connected at 100%. The Chromebook connected at about 75%. This was adequate enough to keep my vpn from disconnecting but it looks like this Chromebook has wifi inferior to my low end, three year old, budget laptop.
As I said before, I am otherwise very happy with this Chromebook, but I wish there was a way to boost the wifi signal.

Unfortunately for upgrade the wifi module (a very simply operation) need to open the notebook and that avoid the warranty...It's not normal that a very new machine like C720 has a poor wifi!

I"m an Amazon Vine member and I just received my C720 today. Everything was going great until the battery got down under 60%. Then, the Chromebook's WiFi began to drop out every ten minutes or so. Now, the Chromebook is at 27%, roughly 3 feet away from the router (which I have moved multiple times... Above the CB, below it, next to it, 10 feet away from it, 3 inches away from it on either side) and the connection is dropping out every minute or so. The drop outs get worse if I leave the CB idle. And before we go blaming the router, it's a MediaLink, the highest rated router on Amazon, which has only had to be rebooted once in three years and has flawless connections to two laptops, an Epson printer, BluRay player and SmartTV. It is not the router.
I have to write my review on Amazon of this CB by December 29th and if this problem can't be resolved I'm going to have to give it 2 stars, because without a network connection the CB is useless, and I'm sure neither Google or Acer want that kind of a review.

I recently received an Acer C720 Chromebook, and I am having the same problem. The Chromebook is sitting three feet away from the router and keeps dropping the wifi connection. It appears to happen more frequently when the battery power drops below 40. I have three other computers (2 Windows laptops and a MacBook Pro) in the same room as the Chromebook. None of them are having a problem maintaining the wifi connection. Since this maybe a problem when the charge is low, I'm leaving the Chromebook plugged in with the charger to see if the signal continues to be dropped.

I have a similar problem with a C720 that I've had for about two weeks. Although the problem wasn't noticeable when I first got the chromebook, it has become increasingly apparent each time I use it on my home network. I have many other devices connected to the same wireless access point/router/DSL modem with no similar problems. I've changed settings on the router as recommended in other forums--no change. The chomebook has no similar problem on work-based wireless network. All comments/suggestions welcome.

When you make hardware at this price point some compromises can be expected. I can certainly confirm that WiFi signals are worse on a Chromebook then many PC laptops. I had a Samsung Chromebook before my Acer C720 and had plenty of WiFi disconnects. But in my opinion considering home dependant a Chromebook is on WiFi. I think I personally would have invested more in a more robust WiFi card. The problem of course is unlike a Windows PC I cannot simply buy a USB WiFi adapter to improve performance. I am stuck with whatever Acer put in these Chromebooks. I am also at the mercy of Google and the Chromium project to update the hardware drivers.

My Acer 720P has just begun dropping its WiFi connection (even when it claims it is still connected). Two other laptops are working great with full signals. The 720 is at 75% and will not stay connected. This problem just began last night. For two weeks, it was fine. This is very frustrating. I am going to have to return it. Too bad, if it worked, it would be perfect.

If you truly have 75% signal I am surprised that your losing connection. I have seen signal levels vary widely from one place to another. I myself have more drops with 2.4ghz band at night when more people are using more WiFi too. Also other close routers can also interfere. I still believe this is a hardware issue with the lousy WiFi card.
