I have a simple network setup. A DSL connection from AT&T connected to a Belkin Play Wireless Router. Two computers are connected through ethernet and have no problems whatsoever.
Any device that connects wirelessly (laptops, desktops, iPhone, iPad, etc.) will connect without a problem (default WPA/WPA2 security settings). However, when browsing/etc (antyhing that uses internet access) it will often act like it is waiting for a response (for about 30-60 seconds) and then either suddenly start receiving or stop (saying it wasn't able to load the page).
As an example, on an iPhone using Safari, after clicking on a link it will act like it is loading but the progress bar does not fill. After the above period of time it will either 1) start loading the page 2) display the message "Safari could not load the website" and then immediately start loading the page or 3) display the previous message and not do anything else.
Signal strength doesn't seem to be an issue as this happens even with a full signal bar.
Have tried both networks (the regular 2.4Ghz and the 5GHz) and they both have the same problem.
Any suggestions as what this could be caused by? It's a difficult problem to describe so I have not found any possible reasons/solutions.
I've had similar issues in the past with different routers (a previous Linksys router would drop the wireless connection every few minutes) that were resolved by getting a different router. The fact that a different router has a similar yet different problem might suggest an interference problem but then it shouldn't be an issue on the different frequency (5GHz) unless there is a lot of interference.
