* Zap the PRAM – Reboot your Mac and hold Command+Option+P+R during restart until you hear another chime, let the Mac boot as usual. * Flush the DNS cache – Launch the Terminal and enter the following command onto one full line within the Terminal:ĭscacheutil -flushcache Mac Wireless Connection Problem Troubleshooting: Advanced * Disable “Wireless G/N/B only” mode – Sometimes a setting is selected that only broadcasts your wireless signal in Wireless B, G, or N mode (depending on the routers abilities). As long as you have the subnet mask, router, and DNS settings configured manually as well, this shouldn’t be a problem. Remember to set the IP to a high number so it wouldn’t interfere with other DHCP machines. * Change DHCP auto settings to manual – sometimes there is a problem with the DHCP server, and if you manually set an IP address on the network you can be fine. * Create a new Network Location – Similar to the above suggestion, try creating a new and different wireless network location to see if it resolves the connection problems. * Delete and recreate connection – Try deleting and recreating/reestablishing the wireless connection, sometimes a setting can be corrupted and this may fix it.

* Make sure router firmware is up to date – Check your router manufacturers website for firmware updates, if there are any available, install them. * Change wireless security protocol – You shouldn’t be using WEP anyway for security reasons, but sometimes changing from WEP to WPA/WPA2 or WPA to WPA2 can resolve wireless connection difficulties. Mac Wireless Troubleshooting: Intermediate
#REMOVE ISTUMBLER MACOS UPDATE#
* Make sure Wireless/Airport card software & firmware is up to date – This is usually done just by going to the Software Update menu, if there are any updates available for your Mac or Airport, install them. Even if it’s a weak signal there can still be interference. * Change Wireless Channels – sometimes your router’s wireless broadcast channel will interfere with a neighbors, be sure you have your router set to a unique channel. Reset this first so the DHCP information will be pulled to the wireless router properly. * Reset your Cable/DSL modem – You’ll usually want to reset this in combination with your wireless router. All you need to do is turn the thing off for a few seconds and turn it back on. You can fix a surprising amount of wireless problems just by resetting the airport/router. * Reset your router – This is the second thing you should try doing.
