“The Linksys MAX-STREAM AC1900 features MU-MIMO, the latest advance toward uninterrupted, simultaneous Wi-Fi connections. Devices such as HD streaming media players, 4K TVs, tablets, and game consoles use a lot of bandwidth. But with MU-MIMO (Multi-User, Multiple-Input, Multiple-Output) technology, the MAX-STREAM AC1900 sends advanced Wi-Fi to multiple devices at the same time and same speed. Your whole family can play, stream, and work at once, without experiencing lag or buffering - at up to 2x the speed of a non-MU-MIMO router.”

The specs include:

  • Wi-Fi Technology: AC1900 MU-MIMO Dual-band Gigabit, 600+1300 Mbps 
  • Wi-Fi Speed: AC1900 (N600 + AC1300) 
  • Wi-Fi Bands: 2.4 and 5 GHz (simultaneous dual band)
  • Power Antennas: 3x external, dual-band, detachable antennas
  • Operation Modes: Wireless Router, Access Point, Wired Bridge, Wireless Bridge
  • Processor: 1.4 GHz dual-core 
  • Number of Ethernet Ports: 4x Gigabit LAN ports, 1x Gigabit WAN port
  • Other Ports: 1x USB 3.0 port, 1x USB 2.0 port 
  • Storage File System Support: FAT, NTFS, HFS+

Retail pricing is $199.99, placing it $50 below the larger 4x4 MU-MIMO EA8500 router ($249.99). If you’re looking to upgrade your router to take advantage of MU-MIMO technology (the benefits of which we covered in our review of the Killer Wireless-AC 1535), this EA7500 provides a new, more affordable option.

ASUS has announced a new high-end wireless repeater, and the RP-AC68U boasts dual-band wireless AC1900 speeds, and features 5 Gigabit Ethernet ports to add wired devices to the network.

ASUS-RP-AC68U-1.jpg

"ASUS RP-AC68U works by connecting wirelessly to an existing router and extending the Wi-Fi signal to areas of poor coverage, which are often a problem in large or multi-floor homes. With its blindingly-fast up to 1900Mbps combined speeds (600Mbps on the 2.4GHz band and 1300Mbps on the 5GHz band), RP-AC68U is the perfect companion for extending the coverage of the latest 802.11ac routers, but it can also be used with routers supporting any older Wi-Fi standards."

The boxy shape is a big contrast from the giant spider-like designs we've seen from recent high-end routers, and inside the enclosure there are a total of 3 transmit and 4 receive antennas to extend the range of your dual-band 802.11ac network.

The RP-AC68U has five Gigabit Ethernet ports on the back, which ASUS says "allow users to convert any wired network devices to wireless operation", and there's a USB 3.0 port to allow additional devices to be added to the network. 

Specifications:

  • I/O ports:
    • 5 x Gigabit Ethernet LAN RJ45
    • 1 x USB 3.0 port
  • Antennas: 4 x Internal antennas (3 transmit, 4 receive)
  • Memory: 128MB Flash / 256MB RAM
  • Operating Frequency: Dual band 2.4GHz & 5GHz
  • Wi-Fi Data Rate*:

NVIDIA Stops SHIELD Android 6.0 Update After Wi-Fi Issues

Subject: Mobile | February 4, 2016 - 02:39 PM |
Tagged: wi-fi, shield tablet, shield, ota update, nvidia, android 6.0

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."

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 driverfeedback@nvidia.com".

New Intel PCN Addresses NUC Overheating Issues

Subject: General Tech, Cases and Cooling | July 20, 2013 - 07:29 AM |
Tagged: Intel, dccp847dye, nuc, SFF, pcn, wi-fi

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.

New Quantenna QSR1000 Chip Will Power 802.11ac Devices, Delivers Up To 1.7Gbps Throughput

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.

qsr1000.jpg

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.

Qualcomm Atheros today launched two new networking cards for the desktop and laptop markets. A subsidiary company of Qualcomm (formerly Killer Networks), the Wireless-N 1202 and E2200 provides Wi-Fi and Ethernet connectivity based on Killer Networks’ technology.

Qualcomm_Atheros_blue_big.jpg

The Wireless-N 1202 is a 802.11n Wi-Fi and Bluetooth module with 2x2 MIMO antennas which should provide plenty of Wireless N range. On the wired side of things the E2200 is a Gigabit Ethernet network card for desktop computers. Both modules are powered by Killer Network’s chip and the Killer Network Manager software. The software will allow users to prioritize gaming, audio, and video packets over other network traffic to deliver the best performance. Director of Business Development Mike Cubbage had the following to say.

“These products create an unprecedented entertainment and real-time communications experience for the end user by ensuring that critical online applications get the bandwidth and priority they need, when they need it.”

The E2200 Gigabit Ethernet NIC is available for purchase now, and the Wireless-N 1202 module will go on sale in May. More specific information on the products will be available after the official launch date (today) so stay tuned to PC Perspective.
