Network speed between a given system adapter and the network Router is determined by the slowest network device. If the Router is an N Router, then your adapter mode is set for G. The problem is likely your Intel AGN Adapter settings - it's Wireless Mode is likely set to G, B/G, or A/B/G, but the N Mode setting probably isn't Enabled, which overrides the other Wireless Modes. Prior to the procedures below, go to Linksys Support, look up your Router, then download the latest firmware update. If it's the same as what you have, then download that. Linksys Support Standard Procedure for any Linksys Router problem with speed or signal begins with flashing the firmware prior to adjusting any other settings. I've added settings for your Router to match your adapter since I have the same hardware. You can look for your Router's firmware update at Linksys Support Enter your Model # and go from there to get the firmware update. The following assumes you have a Linksys Single Band N Router; though these settings are from my Linksys WRT600N Dual-Band, the Admin Panel is the same, except for the extra 5ghz Band setup on mine. Just in case, I've also added the 5ghz settings. With these settings and the AGN or my Linksys WUSB600N DBN Adapter, I average better than 200mbps+, usually around 240 or 260mbps. The settings for the AGN adapter after these settings are matched for the Router settings. On your Router: Access the Router Admin Panel & Wireless Settings from your Browser - http://192.168.1.1/BasicWirelessSettings.htm 1. Click on the Administration link in the Admin Panel - it's on the right hand side. 2. At the very bottom, click on Backup Configurations -save the file to a convenient location on your drive. If you don't save your configuration, you'll have to setup your Router all over again if you've already made any custom changes. The flashing process restores the Router to its default configuration. 3. After backing up the configuration, click on Firmware Upgrade (top right under Administration) 4. Where it says Select a File to upgrade, browse to the update you downloaded, then start the flashing process (flash means install). 5. After the process is completed, and still under the Administration tab, click on the Management link on the left side. 6. At the bottom, click on Restore Configurations. Go to the file you backed up earlier. 7. Check the following are enabled (check box checked) - UPnP (Plug 'n Play). 8. If you wish to have the ability to change your Router settings from your notebook via wireless connection, enable the following under Management also: Web Access - Enable both HTTP and Web Utility Access via Wireless. Remote Access - Remote Management - Enabled, Web Utility Access - HTTP, Remote Upgrade - Disabled (enable if you want remote firmware upgrade ability), Allow Remote IP Address - Any IP Address, Remote Management Port -8080. UPnP - UPnP - Enabled, Allow Users to Configure - Enable, Allow Users to Disable Internet Access - Disabled. Click on "Save Settings" at the bottom of the window, and wait for the Router to complete the save. If you don't and you go to another panel, the settings will have to be done again. After that, click on the Wireless tab, and Basic Wireless Settings. 2.4ghz Wireless Settings 1. Network Mode: Wireless N 2. Network Name (SSID) - Set to a unique name that you can recognize. Enable in checkbox at the bottom to broadcast. 3. Radio Band - 20mhz Standard Channel 4. Wide Channel - Auto (DFS) 5. Standard Channel - Should be grayed out. 6. SSID Broadcast - Enabled Having a unique SSID broadcasted ensure that you or your family won't accidentally connect to a neighbor's network that may have a Linksys Router, but didn't change the default SSID from "Linksys". With today's N routers and their ranges, it's easy to pick up another neighbor's network. FOR DUAL-BAND WIRELESS N ROUTERS ONLY 5ghz Wireless Settings 1. Network Mode: Wireless N Only 2. Network Name (SSID) - Set to a unique name that you can recognize. Enable in checkbox at the bottom to broadcast. 3. Radio Band - 40mhz Wide Channel 4. Wide Channel - Auto (DFS) 5. Standard Channel - Should be grayed out. 6. SSID Broadcast - Enabled Save the settings when complete. Click on Advanced Wireless Settings on the right side. I have my particular Router's AP Isolation Enabled (default is disabled) since I have a lot of network devices and electronics. If you click on the Help link, it will explain what it is. You determine if you wish to enable yours or not. Other settings: Check their actual settings against the defaults listed next to them, especially the N Transmission Rate and Transmission Power. If you have Dual-Band, it's the same for both the 2.4ghz and 5ghz networks. If they're all at default, then click on Wireless Security (no need to save unless you make a change). Wireless Security - I personally don't use any Encrypted Security because it causes multiple server drops during online gaming with N routers. Instead, I use MAC Address Filtering. If you want to use a Security setting, then use WPA2-Personal. Select AES for the encryption method, enter a passphrase (password), then save the settings. Set both to the same if you have a 5ghz network as well, unless you want to have 2 separate passwords. Remember that when you're done, you'll need to enter the passphrase into your Network Connection Profile on your notebook and any other system connecting to your Router. Save the changes. When complete, click on Wireless MAC Filter. Wireless MAC Filter - While you probably don't use this, I do instead of WPA2. What MAC filtering does is allow you to put every device on your network that you wish to have access to the Router on a list, using its MAC Address as the device ID. Once set, only devices on the filter will be able to have access to your network - any other systems or devices can't connect. All you need to do is to Enable the filter, and then add the MAC addresses for each device, including your systems, adapters, any wireless peripherals, etc. If you need help finding the MAC's for your notebook, go to your Control Panel, click on Performance and Tools, then Advanced Tools on the left column, then scroll down and click on View Advanced System Details in System Information. In the System Info window, open out the System Summary tree, the click on the Components tree. Click again on Network, then Adapter. You'll have to scroll down, but you'll see all the MAC addresses - add them all. Make sure that under Access Restriction (top of filter list) that you enable "Permit PCs listed below access to the wireless network" Save settings. Click on the Setup tab. The following should be set: 1. Internet Connection Type - Automatic Configuration - DHCP 2. Optional Settings - Domain should already have your ISP domain information entered. MTU - Auto. 3. Router Address - s/b 192.168.1.1, which is the default for all Linksys Routers (and many other brands as well) but you can change it if you wish. Just remember what you change it to or you'll have to reset your Router to factory defaults. 4. DHCP Server - Enabled. Users - mine's set to 50, and my starting IP is 192.168.1.100. This is helpful if you run a PS3 or other devices and you want to separate their IP's into specific addresses that you want. For example, my PS3'd Dual-Band Adapter address is 192.168.1.75. If you have game console and want specific setups, let me know and I can give you those too. 5. Time Zone - wherever you live. Save Settings. Click on Advanced Routing, ensure that NAT (Network Address Translation) is Enabled. Save Settings if needed. Click on Applications and Gaming, then Quality of Service (QoS). Using Quality of Service allows you to give an application or network device (e.g., an AGN adapter) priority access to the Router over other devices. This is good if you've got family that downloads a lot and you've got important things to do, like stream game data.:manwink: 1. Wireless - Set WMM Support to Enabled (default). 2. Internet Access Priority - Enabled. 3. Category - Select MAC Address. 4. Enter a Name - Intel Wi-Fi AGN 5. MAC Address - Enter your Adapter MAC address (remember you can get it from your System Information) 6. Priority - Medium Click on Add. The new addition will show at the bottom. Before closing the Admin Panel, go back to the Administration tab, and Backup your configurations again. This will save all of the changes you've just made, and allow you to restore them if you ever need to restore the Router to factory default settings in the future. SETTING UP THE INTEL WI-FI AGN ADAPTER FOR A LINKSYS WIRELESS N ROUTER If you weren't aware, the AGN adapter has its own diagnostic toolset. You can access them in the Network and Sharing window - look on the lower left column. It's titled Intel PROSet Wireless Tools. Run them to verify your adapter is working properly. AGN Adapter Settings There's a couple of ways to access the adapter properties: 1. Open your Control Panel, click on Network and Sharing, then Manage Wireless Networks. Click on Adapter Properties. OR 2. Open your Device Manager, right click on the adapter, then click on Properties.
