  • Mozilla Firefox: Arrow keys move cursor within the wepage, rather than scrolling. How to fix?

      This one seems to be a common issue that people with children and pets encounter; a button-mashing session between said small being and the keyboard can sometimes leave your browser moving a cursor around the webpage when you press the arrow keys, instead of the keys scrolling the webpage up and down. Fortunately it’s…

  • XenServer 6.2: NICs showing as disconnected despite being connected

      Sometimes if you connect a network cable to a NIC XenServer doesn’t register it and keeps the status as disconnected; if this happens, try the following via SSH (or from the console, though you will be kicked out of XenCenter once you do it):   xe-toolstack-restart   It may take a little while for…

    New CentOS WordPress install: Error 500

  • Network Troubleshooting: Wireless N connecting at 54Mb/s

      This one came up today with a customer who was extending her Wireless N home wifi network with a wireless access point. The access point was reporting a Wireless N connection at a speed of 54Mb/s rather than 150 or 300Mb/s, and transfer speeds for anything connected to the access point were only 2-3MB/s…

  • Error Code 60 on an Asus Z9PE-D16

      Today a customer’s Asus Z9PE-D16 wouldn’t boot and displayed the debug code 60 – in this case the problem was that the RAM sticks (8 total, 4 for each CPU) were in the black slots rather than the blue slots. Swapping them across resulted in a boot straight away.   Hope that helps someone!

  • Asus P8Z77-V Deluxe not recognising IBM M1015

      We had a customer who installed a M1015 into their workstation and it wouldn’t recognise the card at all during the boot process; the board was still on the shipping BIOS 0906, and the issue was resolved by updating to the most current BIOS (1401 at the time of writing). After updating the BIOS…
