Not the most technical minded guy but wanted to ask the experts about a wireless problem. I have a 600MHz G3 graphite iMac with an airport card in it with firmware 9.52. I was using a Linksys WRT54GL router to create my wireless network which the G3 had no problem connecting with on the 2.4GHz band. Upgraded to a TP-Link AC1750 dual ban gigabit router which supports 802.11b/g/n and ac. I created two networks and set both 2.4 and 5 to run concurrently. Everything went smoothly and my iPad Air recognized both wireless networks and works fine. But I can't get my wireless to work on the G3. It keeps failing to recongize the 2.4 network when I choose it or says the password is invalid. Tried trouble shooting by checking the settings on the 1750 to see if I needed to try and copy certain setting and do something manually but that turns out to be beyond my payscale it seems. Is the simple answer that the new router is just too far advanced for the G3 airport card in it to work? Or is their something I can do manually to get it to connect or am I missing a step somewhere to get it to work. Thanks so much for any help.
