 Ships With Setting Which Destroys Download Speed, 

By 

G. Mueller

After installing this router, my download speed (wireless) went from 15mb/s to 0.5mb/s. After some googling, I found that this router ships with a setting that is enabled, which destroys download speed. After correcting this, download speed increased to 25mb/s. That's why there are so many refurbished units available for purchase. Anyway, do this:
1. Login to your router. If you've never done this, look for instructions that came with your router or do a google search to find the default username and password.
2. Find a page that has QoS settings. For the E1200, you need to click on "Applications & Gaming" and select the "QoS" sub-menu.
3. Disable WMM Support.
4. Click save.

 Could have been good,

Got this router in a few hours ago, initially it seemed to be working fine, when I connected it and setup wireless encryption speeds were holding steady at the expected 58mbps on my network side.
I then connected 3 computers, each with a wireless N router, the first problem I noticed with the router was a signal that was far weaker than I expected, a wi-fi analyzer showed the signal strength to be at 75dbm at less than 30 feet away, after watching it for a while I noticed that the signal strength was fluctuating erratically (to my knowledge there weren't any other nearby wireless devices that could have been causing interference).
I then connected a desktop and tried some online games through the wireless (wireless isn't ideal for gaming, but with a steady connection it is usually sufficient) I noticed that I seemed to be getting an unusual amount of latency, after checking with a few people to confirm that the problem was on my end I started checking pinging the router to monitor communication times between it and my computer, mostly it maintained a good low ping of just a few ms, but a fairly significant number were extremely high, between 1000, and 1200 ms, this happened on multiple network cards while I was pinging the router, I also tried pinging, and running tracert on a few sites I had confirmed were online and would allow pinging (google) the only pings that were dropped, dropped at the router.

Generally I don't have a problem with buying refurbished computer equipment, because it has usually been repaired to like-new specs and can save you a few bucks, this time it doesn't seem to have worked out too well.

If you're willing to take a bet on the router not working to save a few dollars I'd say go for it, otherwise spend a few bucks extra and get a new one or something of a bit better quality.

LEDs near Caps Lock and Number Lock keys blink for hp compaq

LEDs near Caps Lock and Number Lock keys blink

 The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up. If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition.

 Caps Lock/Num Lock LED Component Tested Error Condition
LEDs blink 1 time CPU                CPU not functional
LEDs blink 2 times BIOS             BIOS corruption failure
LEDs blink 3 times Memory         Module error not functional
LEDs blink 4 times Graphics        Graphics controller not functional
LEDs blink 5 times System board General system board failure
LEDs blink 6 times BIOS             BIOS authentication failure

 Knowing the number of blinks is helpful when you contact an HP support agent for technical help. and Computer shop.
