![]() (If you can’t determine dual-band capability from a label on the router, logging into the Wireless section of its admin console will tell you for sure.) But if yours supports 802.11n and is of fairly recent vintage, there’s a good chance it features dual-band operation, which lets it broadcast Wi-Fi networks on both 2.4 and 5 GHz bands. Wi-Fi routers most commonly operate on the 2.4 GHz band. It comes with the Wi-Spy Mini USB spectrum analyzer, which can detect interference from radio frequency (RF) sources other than Wi-Fi networks (such as microwave ovens, cordless phones, Bluetooth devices, etc.). Other tool options include a $10 Android version of inSSIDer (sorry iOS users, Apple doesn’t allow such utilities), as well as a pricier ($249) and more powerful inSSIDer Office-designed for offices with multiple access points. This $20 diagnostic tool, which runs on Windows or Mac, clearly shows you which channels any nearby networks operate on and recommends the best channel to minimize interference for your network. To see which networks are using which channels (and may be overlapping with each other), use MetaGeek’s inSSIDer 4. When two or more Wi-Fi networks fight over the same frequency, the result can be slow speeds and/or tenuous connections.Īny Wi-Fi-capable device will indicate what other Wi-Fi networks are operating nearby, but that’s about all they’ll tell you. channels-at 2.4 GHz, there are only three that don’t overlap). Unless your office is in the middle of a cornfield, it’s probably not the only Wi-Fi network in the immediate vicinity, and when multiple Wi-Fi networks exist in a relatively confined space, they’re often locked in combat for access to the limited number of available wireless frequencies (a.k.a. Depending on how you’re set up, your Wi-Fi hardware device may be best described as either a gateway (which usually integrates a cable or DSL modem) or an access point (which strictly does Wi-Fi.) In any event, most of these tips should apply to whatever type of Wi-Fi device you have. We’re also going to use the term Wi-Fi “routers” throughout this article in reference to devices that broadcast a Wi-Fi network and also connect to the Internet by connecting to and/or integrating ISP-provided equipment. ![]() In some scenarios you may be able to improve only one or two of these characteristics. the ability to accommodate more devices at an acceptable connection speed), or some combination of the three. Before we get to the tips, note that increased performance might mean faster connection speeds for your devices, greater range for your network, higher capacity (i.e. This month we’re back with tips on how to you can improve Wi-Fi performance, often with minimal cost or effort. I noticed that for Australia there is a more recent firmware.A couple of months ago we offered tips on how to improve security on a small business Wi-Fi network. I tried to update the firmware using the image in the revA1_1.01_eu_10232013.zip file, but it failed. In the ftp site I can see that there is another firmware: The device reports that firmware is EU_1.00 03202013Īll the European web sites for the device, report that the latest firmware is from date. Naturally I looked for a firmware update. ![]() Router says the wireless is on but it's not detected by any client, even from half meter distance.Īll the other functions of the device work fine. ![]() I've tried everything, changing ssid, channel, transfer rate, network visibility, encryption method, disabled wps, reset router to factory defaults, running the setup program from the Windows CD. I'm an IT professional, I'm familiar with all the options in the wireless configuration. In the Wireless Setup page everything is ok, the status reports that Wireless is enabled, the wifi led in the front is on.īut none of my wireless clients (laptop, two mobile phones, printer) can see my wifi access point anymore. After switching on, the wifi is no longer detected by any client. I have a DSL-2770L router (bought in Spain). Quote from: pH7 on December 09, 2013, 08:39:39 AM Hi, this is a weird case.
