My DIR-615 worked fine for two days, but from there on I have extremely limited speed throught the wireless connection. Internet speed using the cable (through the router) is stable at 5.5 MBps, close to what is promissed by my provider. Throught the wireless I have never more than 200 kbps, sometimes less than 20 kbps. This happens in different laptops and smartphones, also when only one of them is connected. Large delays are also appearing intermittently. I've tried changing the channel, but it didn't help much. Using my notebook to generate the wireless network I get much better and stable speeds (around 3MBps).
Any ideas why this could be happening?
Thanks in advance.
My Firmware-Version : 4.10 ,
