I had set up the router a few months ago to reflect the two channels it delivers, 2.5 and 5.0 GHz respectively. Some of my applications that use the router select 2.5 like a Kobo reader and the Sony PS3. At the moment as WiFi goes only my Sony Xperia phone connects to the 5.0 GHz channel. > The OP should be looking at syslog and/or the journalctl output.

Thanks for all the suggestions they don't hurt because when looking into one thing something else comes up. I really didn't have a faulty setup for the Penguin USB N type WiFi adapter as I originally thought. I installed a driver from the Penguin site directly into the /lib/firmware directory, the 9k_firmware_free-version/htc_9271.fw I rebooted the computer but this didn't light up the USB adapter. I tried all the available USB sockets and rebooted a few more times, stuff like that, but the Penguin was dead. I was fed up and went to bed shutting off the computer. During the night there was a miraculous like occurrence. When booting up the next morning the 'dead' USB adapter now came on and started trying to connect to the router. Success right? Wrong. Later in the day I was reading about setting up these wireless adapters and ran across this valuable command: #iwlist wlan0 scan by that command all was revealed. There were 19 cells in a 50 yard radius of my adapter (with a hi-gain antenna) including my router but (I guess you've figured it out by now) the adapter or the firmware doesn't 'see' the 5.0-GHz channel. Completely invisible. Only the 2.5 GHz channel was listed in the wlan0 scan. My /etc/network/interfaces file was set up like this: # # # The wireless network interface auto wlan0 iface wlan0 inet dhcp wpa-ssid dlink-5.0GHz <what's wrong with this ssid entry> wpa-key-mgmt WPA-PSK wpa-psk <the passphrase> anyway by changing wpa-ssid dlink-5.0GHz to 2.5GHz the adapter connected promptly and voilĂ . After all that, joy did not manifold. The down speed of the connection was no good. I pay for 20 Mbits from the cable company but..that depends. This is a Debian story. I ran the Ookla speed test (speedtest.net) connected through the Intel Ethernet card in the PCIe slot wired to the back of the router and speedtest did show 21Mbits. (middle of the morning on a business day) 5 minutes after that the best the USB wireless N adapter could do was 7.0 Mbits down speed. I'm looking into a PCIe wireless card duel channel adapter as an upgrade. Any good experiences out there with a particular kind (for desktop computer with PCIe slot) with free or non-free firmware I would like to hear your story.
