NVIDIA has pulled the Android 6.0 OTA update for the original SHEILD (pre-K1) tablet after users experienced wi-fi connection issues. A post on NVIDIA's official forums explains:
"We have temporarily turned off the OTA update until we understand why a few users are losing WiFi connection after updating their tablet to OTA 4.0."
(Image: Android Police)
The post is authored by Manuel Guzman of NVIDIA Customer Care, and includes a list of potential fixes:
- Reboot your tablet 2-3 times. If this fails, power cycle your tablet 3-4 times (not reboot but complete power off). If this does not work, charge your tablet to 100% and attempt again a couple of times or so.
- Factory reset your tablet. Make sure you backup any important files before you perform this step.
- A couple of users reporting their WiFi coming back after leaving their tablet powered off for a few hours. Try leaving your tablet powered off for a few hours and then turn the device back on.
Users who still have issues connecting are asked to navigate to the Advanced W-Fi page on their tablet, and then to "take a screenshot and email the picture to firstname.lastname@example.org".

Intel recently posted a Product Change Notification (PCN, number 112432-00) regarding one of its first NUC bare-bones systems, model number BOXDCCP847DYE. The PCN seeks to address the overheating issues that several hardware review sites encountered when performing large file copies across the network using the built-in Wi-Fi card. Intel has reportedly found a solution by adding a 9.5mm thermal pad to the underside of the top cover. The thermal pad will make contact with the mSATA SSD and facilitate heat transfer from the drive into the metal chassis.
The overheating problems spotted by PC Perspective (in our review) and other tech sites lead to system freezes and restarts. When transferring large amounts of data across the network, the built-in mPCI-E Wi-Fi card would heat up, and because the SSD is mounted just above the Wi-Fi card, the system would lock up or crash when the SSD overheated. Thus, Intel’s workaround is to improve the cooling of the SSD such that it (hopefully) will no longer overheat and users will not have to resort to buying a USB Wi-Fi dongle or running an Ethernet cable to the switch.
According to the PCN, the solution works and system retailers should expect shipments of the BOXDCCP847DYE with upgraded cover to arrive as early as August 1st. Notably, Intel is planning to ship out all pre-modification inventory before moving onto shipping updated bare-bones systems. It may be some time before consumers can be sure they are getting the updated model. In the meantime, users can always opt to use one of the many third party NUC cases that take full advantage of passive cooling techniques.

Tagged: wi-fi, quantenna, qsr1000, mu-mimo, 802.11ac
Quantenna, has announced a new 802.11ac QSR1000 chip that is capable of delivering up to 1.7Gbps throughput. The new chip achieves the wireless throughput by supporting a combination of Multi-User MIMO, four spatial streams, 256-QAM modulation, and beamforming technology. More information on 802.11ac and the related technologies can be found here.
The Quantenna chip is a competitor to Broadcom's offerings and it is intended for use in wireless routers, access points, Set Top Boxes (STB), and other consumer electronics gear. It is the first "wave 2" (second iteration of the 802.11ac specification) 802.11ac chip, and is the fastest so far. Quantenna was able to get a theoretical max of 435.2Mbps of throughput per spatial stream, which is pretty impressive. Unfortunately, client devices (computers, smartphones, tablets, et al) will also have to support the MU-MIMO technology and have the hardware to transmit and receive multiple streams to take full advantage of the 1.7Gbps max throughput.
There is no word on which upcoming wireless devices the Quantenna chip will be used in, but the company is making the new QSR1000 chip available to manufacturers as early as Q3 of this year. Actual routers and other gear using the chip and widely available to consumers will likely not hit the market until early next year, however.
