If you find that the plastic flap on the USB sockets is annoying you, it can be easily removed, its got C shaped clips that are 90 degrees to the face, so if you open the door, you can pop it off gently by pulling it horizontally away from the unit, like pulling the USB devices out. If you pop the PCB out, the front-left aerial next to the USB socket is horizontal and mounted on a bracket, so it needs to be nudged to get it to pop back into its holeĪssembly is the reverse of above, just make sure that the PCB is on the locating lugs in the plastic before you drop the cover back on and slide it into position. Note that the board can't be lifted out with all the aerials still attached and if you tip the PCB, the power cable will come out too (more on this later) and the aerial cables are not very loose with all the tape they have assembled the unit with, so take care here not to damage anything. There are no screws holding anything in, so thing are now loose. Gently slide the bottom cover backwards towards the Ethernet sockets, it moves about 10mm With the unit upside down with the Ethernet sockets facing away from you, remove the 4 plastic feet to show the T9 torx. Remove any USB devices, since the plastic cover can't be removed with them in.Ģ. I'm going to post this in several posts as there is a lot of info.ġ. OK, so I took the plunge an decided to see how hot it was getting internally. Posted: Thu 16:18 Post subject: Dissassembly and temperatures The device also states a 100,000 *typical* write cycle endurance and that it has 4 bit ECC per 528 bytes (x or 264 words (x16), but clearly the firmware would have to check for ECC errors, again I don't know if it does that. CFE, Firmware, NVRAM and built in JFFS being all on the same chip. I understand from other Broadcom based devices that the NVRAM is partition mtd/3 that is carved up from this chip. The device has a thermal envelope of -40 to +85 degrees C. Īpparently the R8500 has a Spansion S34ML01G200TF100 NAND device in it, Spansion has been purchased by Cypress (see ) and the data sheet for the FLASH chip is here.

I really need to crack this puppy open and see what the heat sink says. A quick check against the scant information on Broadcom and confirmed that (on a Russian site) at least for an earlier generation CPU. Given that this is outside on the poor thermal conducting plastic and not the heat sink below, then its going to be hotter and again, the devices below the heatsink will be hotter still.įrom memory, the maximum "junction temperature" inside most chips is 125 degrees C. The router is measuring 51 degrees on the top and 52 degrees underneath on the label. Its currently 25 degrees in my house and and 27 in my office. I did a quick test on my device with an infrared thermometer. Remember that the Broadcom CPU's like most modern ones have thermal envelope protection, so they slow down if they get too hot (thus the slower performance observation by others) The trend seems to be high temperature, random reboots, slowing in performance over time, etc. This implies that there is a hardware issue here. Seems that some have had warranty replacements with some success, others not. Netgear support and Amazon reviews all say the same sort of thing (and highlight a 90 day "free phone support", as apparently its paid after that, which is far less than ideal, or what I would expect on a top-end device. My current gut feel, having spent some time trawling around the interweb reading reviews (that I should probably have read before purchase if I knew then, what I know now) is that this is a thermal issue. It might help in some situations, but I don't think its going to fix this issue. I don't know if dd-wrt does this already.

Reads don't have a cost on the devices lifespan either. The concept of a read-after-write verify on something is not new, tape drives have done that for ages (sometimes with two heads, one read, one write). Posted: Thu 13:58 Post subject: Read after write and temperature
