Power Saving Mode-> Choose Maximum Performance.Reset the TCP/IP Stack SettingsYou should also make sure that the TCP/IP stack with standard settings is used on this computer. To do it, reset the settings of the TCP/IP stack to default with netsh:netsh int ip reset C:\resetlog.logIf you receive an error “Access is denied” for any of the components when you perform a reset, you need to give your account Full Control in the properties of the following registry key HKLM\SYSTEM\CurrentControlSet\Control\Nsi\ {eb004a00-9b1a-11d4-9123-0050047759bc}\26. After that, run the command again.After the command has been run, restart the system, connect to the Wi-Fi access point and try to access the Internet.Disable TCP/IP AutotuningIn Windows Vista / Windows Server 2008 a new feature, TCP Receive Window Auto-Tuning, was introduced to dynamically resize the size of the acceptor’s memory buffer (due to this feature, the maximum size of the transfer window can be increased to 16MB). In theory, this one should improve the efficiency of using network bandwidth and optimize the performance of the network subsystem. But in practice, autotuning of the Receive Window (RWIN) size results in many network issues. In Windows 10, as in Windows 8.1, TCP RWIN Auto-Tuning was preserved and sometimes the TCP autotuning means conflict with the settings of network equipment or firewalls (it doesn’t support or prohibit TCP Window scaling) causing package loss and the speed of the local network or the Internet decreases or even the completely access lost.So we recommend to disable the TCP/IP autotuning. To do it, open the command prompt with the administrator privileges and run the following commands one by one:Tip. These commands are usually 100% effective on devices with Windows RT (including Surface), but can also help on desktop versions of Windows 10 / 8.1.netsh int tcp set heuristics disablednetsh int tcp set global autotuninglevel=disablednetsh int tcp set global rss=enabledTo check if the TCP/IP autotuning is disabled, use the following command:netsh int tcp show globalAfter you run all the commands, restart your computer.Update the Wi-Fi Adapter DriverTroubles with Wi-Fi adapter drivers can be another source of problems. Try to update the drivers to the latest version available on the manufacturer’s website. If the issue of the limited Internet connection is not solved this way, try to use the older version of the driver. More on this in the next section.Downgrade (Rollback) the Wi-Fi Adapter DriverAnother effective technique for troubleshooting a Wi-Fi connection is the rollback to the older version of the wireless adapter driver.Tip. The option of rolling back to the previous version of the adapter helps almost in 100% of cases when the problem with a limited Wi-Fi connection for users appeared after upgrade to the next Windows 10 build, especially for the devices with Wi-Fi adapters Broadcom 802.11 and Qualcomm Atheros AR9003WB. Most likely, the cause of the issue is an incorrect version of the new wireless drivers in the new builds of Windows 10.To roll back to the older version of the Wi-Fi adaptor driver in Windows 10 / 8:Open the Device Manager

The acquisition is intended to help Qualcomm grow beyond cellular networks Qualcomm has entered into an agreement to purchase chip maker Atheros for US$3.1 billion, or $45 per share, in cash, the company said on Wednesday.Qualcomm has entered into an agreement to purchase chip maker Atheros for $3.1 billion, or $45 per share, in cash, the company said on Wednesday.Watch a slideshow of the 2010 tech M&AsThe transaction has been approved by the Qualcomm and Atheros boards of directors and is expected to close in the first half of 2011, Qualcomm said in a statement.By acquiring Atheros, Qualcomm is hoping to help expand the use of its products beyond cellular networks, according to Qualcomm. The company’s strategy is to continually integrate additional technologies, including LTE (Long Term Evolution) and HSPA+ (High-Speed Packet Access), into mobile devices. The acquisition of Atheros will extend that strategy into other types of devices, it said. Compared to mobile broadband, Wi-Fi is used in a wider array of products, including game consoles and media players.Atheros is most well-known for its Wi-Fi chipsets. But the company also makes components for other technologies, including Bluetooth, Ethernet and GPS. For example, on Monday, the company announced a power-efficient combination of chips for Bluetooth and IEEE 802.11n Wi-Fi, which can be used in notebooks, netbooks, desktops and tablets.The Wi-Fi market has experienced healthy growth lately, a growth that Qualcomm will be able to tap into if the acquisition is approved. Worldwide wireless LAN equipment revenue grew 14 percent sequentially in the third quarter of 2010 to $680 million, continuing a trend of positive growth from the market, according to market research company Infonetics Research.Also, the use of Wi-Fi hotspots will continue to grow in the next couple of years. Worldwide annual hotspot connects, or sessions, amounted to more than 2 billion by the end of 2010, and are anticipated to grow to over 11 billion by 2014, according to market research company In-Stat. Because today’s smartphones are expected to be equipped with an ever growing number of wireless and mobile networks, the more integrated they are with each other, the easier and more cost efficient it becomes for vendors to implement them.Atheros’ CEO Craig Barratt is expected to join Qualcomm as president of its Networking & Connectivity division. Atheros’ shareholders and regulatory bodies now have to approve Qualcomm’s acquisition.Send news tips and comments to [email protected]

(12 fps), but the ASUS U41Jf turned in a much better 62 fps at the max settings.The AS4820TG achieved 74 fps in Far Cry 2 at the standard 1024 x 768 screen resolution and 38 fps in its native resolution, which means it fared better against the competition. The ASUS U41Jf notched 44 and 37 fps, respectively, while the Samsung QX410 churned out only 33 fps and 12 fps at its native resolution.Battery Life and Wi-FiThe AS4820TG lasted 5 hours and 11 minutes on the Laptop Battery Test (web surfing over Wi-Fi), which is about 15 minutes longer than the category average for thin-and-light notebooks. However, the Samsung QX410 endured for 5 hours and 20 minutes, and the ASUS U41Jf lasted an even longer 6:36.The Atheros AR5B97 Wireless Adapter pulled down 25 MBps with a 15-foot connection and 15.6 MBps at a 50-foot distance from the router. Both data rates are lower than the category averages of 33.5 and 21.7 MBps as well as the Samsung QX410's scores (39.9 and 28.7 MBps).We should note that the Wi-Fi card in our first evaluation unit failed to connect to the Internet after a few days. However, a second system equipped with the same Wi-Fi card worked fine.Software and WarrantyAcer bundles the AS4820TG with The New York Times Reader and the Barnes & Noble Desktop Reader for books, magazines, and newspapers, along with less practical additions such as shortcuts to the Netflix and eBay websites. Other pre-installed software includes a free 30-day trial of Norton Online BackUp ($49.99 a year after the trial), a month-long trial of McAfee Internet Security ($39.99 a year afterwards), and a newsreader called eSobi. Last but not least is Microsoft Office Starter 2010, which includes ad-supported versions of Excel, PowerPoint, and Word.Click to enlargeThere are also proprietary programs
