Tech Unleashed: 2024 State of IT Insights on Dec 19, 2023įor the last few years, Peter has been doing a State of IT panel at SpiceWorld, and I usually take a ton of pictures of the slides with even more notes that I want to do topics and articles on.inSSIDer (the free/office version was great, but harder to find today) Wifi Analyzer (for Android) Opens a new window WirelessNetView (for XP) Opens a new window ![]() WifiInfoView (for Vista, 7, 8) Opens a new window Keep in mind WiFi APs, depending on model, are good for only 8 to 50 associated clients, more than the AP can handle and it can crash or have performance issues - maybe it's time to add more APs?Īlso channel congestion can lead to issues, have you done a scan of all the channels around this area? that will allow you to plot a graph over time and see how/when it's "fluctuating" then you can also pinpoint where the problem is. Some other random things on the Internet (or use the default sensor that PRTG creates for "cloud provider check" Put a laptop there, set to never sleep, and connect it to the WiFi, then run Opens a new window (PRTG) on this laptop and ping the following. We had to complain to the FCC on this one as they are not supposed to run their radar when docked at a port). You may need to monitor this over time to make sure it's not some sort of intermediate noise causing the issue (we once had the Navy running some radar tests and every time they swept the radar over us all our wireless connections would drop, it took a few days to work out that this is what was happening. And if all of this checks out (strong signal, clear channel and low interference) then you'll need to dig around in the clients themselves to see if you can work out what's going on. This will at least give you an idea about the physical environment and point you in some direction for improvement. Tweaking the channel could help with this as well. If you noise is strong (strength of 0dBm to around -70dBm) then you may need to look into a using some sort of spectrum analyzer to work out where it's coming from, and on what frequency/channel it's on. Make sure no other wifi APs are interfering with yours on the channels you are using, if there are some, then see about moving yours to a less congested channel (or ideally an empty one).Ĥ. An RSSI of -70dBm to -80dBm would be an ok signal, anything below -50dBm would be considered excellent.ģ. An RSSI above -85dBm would be very poor and it would be amazing if the client was able to do more than connect. You're looking for an RSSI of below -80dBm (above this the signal is unuseable) and a noise level of -80dBm or above (an snr of 50dBm or higher). Grab a wireless client and go into those areas and check the signal strengths and noise-signal ratios. Then map out where the complaints are coming from.Ģ. Grab a map (or make a map) of the coverage area, include walls, appliances, printers etc. You don't even mention if you're talking 2.4Ghz or 5Ghz.ġ. It was just strong enough for the client to connect and do some browsing, but then the signal would randomly drop. I've had this same sort of thing happen to some of my users and in my case it was a weak signal. If this is the best I can get out of a brand new device, that is supposed to be able to transfer at 300 Mbps, then I'll be taking it back and exchanging it for another brand.You're going to have to collect a ton more data on this. The settings of my Wifi on the router are as follows:Ĭhannel Width: Auto (set to auto on laptop as well)Įnable WMM: Off (This is because of my other post) so that eliminates the question of if the computers are at fault for the transfer. I have also transferred files via the wired network between the same two devices, and I got close to gigabit speeds. I also tried it at a distance of about 6m. The laptop at the moment when testing the transfer rate is about 0.5m from the router. I was able to get better performance out of my old b/g device. The best transfer rate I could get was about 2.5MB/s so that's roughly 20mbps. The desktop computer is connected to the router via the Gigabit switch. I have brought my laptop home from work to transfer some files from my other computer. but I'd also like to know why the performance of the WiFi is so terrible. I have already posted about an issue with this router regarding not being able to enable WMM ( ![]()
