Hi,
I have had my DIR-815 router for a while now and normally connect via ethernet to my iMac no problem. I set up the wireless network using the wizard online and everything worked perfectly for a short period of time (few days).
The ethernet connection to the router works perfectly and is steady providing a good stable internet connection. I have just moved my imac and I am now connecting wirelessly which is also working great, I also use my apple tv wireless and also works great.
However when I am trying to connect using my macbook, or my wife and I's iphones I have issues. They will connect to the internet for a very short period of time 10-15 secs then the network will drop. If I disconnect from the wireless network from the devices and reconnect the same problem occurs, short connection then disconnects.
When I reset both the router and the modem it appears to fix the problem and then the laptop and iphones can then use the wireless fine...for a day or two and then the problem will occur again requiring another reset of router/modem.
Can anyone help me? Its getting annoying how it will work on some devices but not all.
