Use it for wireless site surveys, wireless discovery, and to connect to WiFi networks. WiFi Scanner detects access points and clients in ad-hoc mode if the SSID is being broadcasted. Then re-join the network and let the system re-create clean versions of those entries.NetStumbler is a tool that detects WLANs using 802.11b, 802.11a and 802.11g. No updated version has been developed since 2005. NetStumbler helps detecting networks interference. You might also want to delete those networks' entries from System Preferences > Network > AirPort > Advanced > AirPort > Preferred Networks. Use the Keychain Access utility (in /Applications/Utilities/) to do that. In the case of networks seemingly refusing a correct password, try deleting any saved passwords for those networks from your keychain. ![]() For example, if you're in the UK which like the other EU (ETSI) countries allows channels 1-13, and a nearby, misconfigured AP says "US" which only allows channels 1-11, then clients that see the US AP first may have trouble joining other APs that happen to be on channels 12 and 13. #ISTUMBLER FOR IOS CODE#Are all networks in range reporting the code for the country you're in (if they report one at all)? If any are reporting the wrong country, it can cause some clients to get confused at boot/wake time. Pay special attention to the "CC" (Country Code) column. Try running the airport -s command in Terminal to see a detailed listing of networks in range, that includes some info that iStumbler leaves out:Īlias airport='/System/Library/PrivateFrameworks/amework/Resources/airport' Scanners force the client to repeatedly tune to other channels to look for other networks, which can get in the way of that client's ability to do the right thing on the channel it's supposed to be on for the current network it's trying to join. Walk away, connection drops quite soon at 30 feet then reconnected briefly then died again.ĭon't leave iStumbler or other network scanning tools running on the same machine that's having trouble joining the network. Lots of attempts to Airport on/off, join other etc and suddenly I get to connect, get given new IP (I revoked), can browse. I'd say iStubler is suffering timeouts&hangs but hard to be sure. Right next to DIR655 but iStumbler not showing it, although most other wifi's have gone. Carried MBP across garden towards DIR655, a few other wifis show up on iStumbler, low signals all channel 1. Just revoked the lease for the MBP on DIR655 and no changes although this seemed to help MBP wake into connection 1 hour ago. #ISTUMBLER FOR IOS PASSWORD#(2 mins later):NOW both names ARE visible, but both fail to accept the correct WPA2 password and keep asking again after failing to connect. It also refuses to connect to my garden network (an old Belkin acting as AP wired to DIR655), the signal it can see and even net name in Sys Prefs > Net>Network names Just walked the MBP to the garden office and iStumbler now sees the more distant DIR655 signal although it will not connect to it (does not show under Sys Prefs > Net>Network names) even after airport off & on. Anyway signals all show low interference and high throughput except for this failure to connect. I do not think there are any channel overlaps and we also have RFquiet DECT phones (Orchid) that are silent until lifted or called. #ISTUMBLER FOR IOS HOW TO#So I suspect lease timing/locking issue but unsure how to check up, plus why iStumbler seems to say the network is not visible at all when I sit on the iPad right next to it just fine. If I use the DIR655 admin web and release the lease the MBP has then wake it all worked OK. The DIR655 (hardware rev A3) is on the original EU firmware 1.10, I'm cautious about jumping to latest 1.31EU since no downgrade seems to be possible and that feels a bit risky as so much is set up and working fine. I must admit the winter sometimes seems to loose connect too, but less so. He just resets router and it all works but this does not please me! no ping no en0 or en1 device seems to exist. IStumbler can see 1 neighbours hub and my garden hub are there but can't get to the normal DIR655 wifi. the MBP however frequently wakes and fails to find the internet. ![]() Router signal is fine since iPad, Wintel on same table 20 feet from router are fine. This is my son's MBP 7,1 running Snow Leopard 10.6.7. ![]()
