Wireless networks are valued by end users for their convenience and ease-of-use. But behind every seamlessly operating wireless network out there in the enterprise, there is likely more than one networking guru who has pulled their hair out ensuring the WLAN simply works.

If you're looking for ways to streamline your WiFi operations, we've got 10 tools that help track down channel conflicts, find rogue WLANs, perform network diagnostics, and more. These WiFi troubleshooting tools and utilities are designed to help make the process of WLAN management easier for the IT staff charged with keeping wireless users happy and productive.

Most IT pros are familiar with the classic free NetStumbler utility, which can be used to detect 802.11 a/b/g WLANs and can help in the verification of configuration and identifying weak signals within a wireless network. While other tools have refined the discovery process, NetStumbler still remains a valid option for network administrators. But there are a lot of other WiFi troubleshooting tools out there worth checking out, and some -- like NetStumbler -- are even free.

Re: other tools?
The WiFi Monitor Plus looks interesting, I'm going to give it a try. 

I have over 20 2.4GHZ WiFi networks fighting for spectrum at home. My DSL is working fine because we only have four devices connected to it, but sometimes is difficult to get a good signal.

I believe this is a common issue in condos and big appartment buildings. I wish I had a 5GHz router.

Re: other tools?
Thanks for those details Pablo.

A new free WiFi tool was just released today by ManageEngine; WiFi Monitor Plus lets companies monitor WiFi signals from their Android devices. The company claims its the first to provide both analyzer and surveyor modes.

Re: other tools?
Marcia, the WiFi analyzer is great to use in places where several APs and WiFi routers are in use from different netwroks. Tipically an office building shared by several companies each managing their own network.

A simple tool can help to determine the best channels based on what the other networks are using.

It is also perfect for consumers living in condos where every apartment has a WiFi router.

Re: other tools?
Marcia, for basic WiFi detection and information I like the Android WiFi Analyzer. It supports 2.4 Ghz and 5 Ghz, and gives you a map of all the networks, type of AP and signal strength.

It is not for heavy users, but makes a Smartphone a basic WiFi mobile detection tool.

Re: other tools?
If the environment requires the creation of a hotspot access point, tools that allow for their creation can make the process quicker. The network administrator would be involved in this process, but if rogue networks ever become a major security concern, this makes it difficult for the security team to find rogue access points.
