Ports overheat and fail
357210
The problem is simple: the port(s) overheat and fail. Each time, I have to unplug the accessory and plug it into a different port. Eventually, that will fail too. The failure is temporary, but the problem is not.

Owned this device less than a year and its failing. I suspect it is overheating because after powering it down have to wait > 30 mins for it to cool down before it will reboot. Called Linksys tech support and they want $30 even though its under warranty. Experience has been one or two standard deviations worse than my old Linksys WRT54G. Wish I had bought something else.

one of the two servers kept rebooting..was returned for service.  Otherwise they are decent Laptops.

The power supply overheats. Even at idle there is a hot spot on the side. It must be defective, a high efficiency supply at no circumstances should dissipate this much heat.

One port was bad. Tried different machines, slots, operating systems. Returned and got a PCIe Intel dual.

I have just solved a problem with intermittent WAN connections and overheating with this product.

On hot days (today it's 85 degrees in my office) the D-Link DIR-655 router overheats when handling a lot of local network traffic (copying big files between computers) and drops the WAN connection (to the cable modem). Before this happens, there is short period of intermittent or unreliable connectivity to the WAN. The LAN still works fine, however.

I tried swapping in another DIR-655 router, same problem once the thing warmed up. I added an external fan blowing on the router case, and everything is happy again.

The air-cooling slots in the case are very small, and the case feels very warm (without the fan.)

I have no problem having the extra router, though. After all, a single-point failure of the router kills all my internet connectivity.

Except for the overheating problem, I like this product, the wireless connections work fine, and would recommend it (just think about keeping it cool.)

Purchased in January 2018. As of today, ports 1-3 still work, ports 4-7 provide no power or connectivity to the computer. The three "power-only" ports also continue to function properly. Will try contacting Anker, but I've had trouble with their "customer service" in the past.

Edited to add: Anker did reach out to me, but went completely silent after exchanging information. I guess they all left for the weekend early on Friday, so I'll have to go buy another hub if I want to get anything done.

Mine failed after a few months, and the manufacturer has not responded ro multiple warranty requests.  Try the Asus HS-1000W instead. It's less expensive and has longer range but the manual does warn that it can be damaged by plugging it in wrong.

This was a very nice product overall.  I agree with most of the positive reviews thus far.  The unit overheats.  I am on my second one. It is now overheating even in wintertime in an unheated apartment in western Japan. It will work for about 5 minutes then lock up when the temperature inside the unit gets too high.  This is not a defect in this unit.  The last unit had a similar problem but overheated in summertime and melted down.  This unit melted down its wireless transceiver about 3 months ago but I could still use the ethernet ports for the last few months.  Now those also appear to be failing.  I can only say that this appears to be bad design for cooling.  It really is  ONLY a travel router. I was using it 24x7 for Internet access while overseas this time and also with the last unit 2 years ago.  Don't buy this unit for constant operation.  It can't take the continued use. It will overheat and fail.
UPDATE 3/15/09 - Unit has completely burnt out about 2 months ago.  Replaced it with a $29 IO Data brand box that isn't nearly as nice (but at least it doesn't turn to toast).

Well, I've had this for 2 years. I was able to play Call of Duty Modern Warfare with no problems. Two months later, my computer starts overheating then shutting off. Anytime I play a game that requires the littlest of effort from the video card, it can't handle it. I've even had this thing shut down from overheating while having it connected to a projector for a presentation to my team.

Idle temperatures are way too high and I have even elevated the laptop and put a fan to it to help "cool" it down. Still overheats. And yes, I have shot out all the dust with a compressed air can. Stay away from this. Gateway customer support is a joke. I spent way too much on shipping only to have them send it back after running a version of 3DMark05 once. Did I really just waste my money on having them install a free piece of software that I could have done myself?

Only good thing about this computer is that it's relatively quick with basic processes and that it looks cool. Don't even bother having this on your lap because it will be too hot to handle.

Overheats while writing after less than 30 seconds.  Windows throws errors and informs me that it has found errors on the drive.  Fixing the errors or reformatting does not resolve the issue.

Worked fine for a while. Just tried to use it today and got an error message. Removed it from USB port and it was hot to touch, appears melted!

Heats up pretty fast plus unstable connection.

My experience with this unit has been very poor. It ran hot and would lock up after about 30 minutes of activity so that it would need to be unplugged and restarted. This was with either a static IP address or DHCP assigned IP address. When it worked, it was excellent and I did use it as both a gigabit switch and wireless adapter. When I say it locked up, the Ethernet ports would still operate - but the wireless bridge part of it would stop working. I did update the firmware repeatedly to see if that would help, but it did not.

One of the ports stopped working in under a month grow the date of purchase.  Would not buy again.

Occasionally some of the ports do not work properly and you have to switch that port on and off many times to get it to work.
