I also wanted Bluetooth compatibility (as the Dell Inspiron 1545 doesn’t come with any).Īfter a little research, I found the Intel Centrino Advanced-N 6000-series cards. Secondly, the new card needs to be compatible with 802.11an 5 GHz. The internal card needs to be a “half mini PCI-e card”. So the real question at that point was, which internal cards will work? First off, there is a physical size restriction. No cables/adapters to mess with and no major hit to my bank account. I’ll just replace my internal Dell Wireless 1397 WLAN Mini-Card. So… do I toss out my laptop? Buy an external USB wireless adapter? No thanks. This wouldn’t be such an issue normally but, after testing the two broadcasting bands, I found myself getting only 30% of the speed and reliability of the 5 GHz SSID due to a very congested 2.4 GHz range. My personal laptop is a Dell Inspiron 1545.

Then the pain set in… My personal laptop was not compatible with 802.11an / 5 GHz.

I wanted to avoid this at all costs and decided to enable the 5 GHz radio on my Netgear WNDR3700 v4 running DD-WRT build 22118 (highly capable hardware and firmware combination for a home AP). One of the sore points of living in a city is that you have neighbors lots of neighbors with WiFi APs polluting the 2.4 GHz band.

After recently moving to a new house, I decided to take some time to carefully plan out my home network.
