Hi. I have two laptops connected to Wi-Fi on My DIR-825. While one works OK in both, 2.4GHz and 5GHz (HP laptop), the other one (DELL Inspiron B1300) finds only 2.4GHz network. But this is not a problem at all. The problem is, that the Wi-Fi connection DELL-router is unstable. The Wi-Fi connection DELL - router wokrs for a few minutes (aprox. 5 minutes), then it disconnects and reconnects again. This goes on and on. I have checked settings on router, Wi-Fi driver on laptop, but everything seems to be OK. Do you have any idea, what could be the problem?
