I was wondering how can you determine which component of a wifi network can be at fault for slow internet connection issues. The question has arosed from a situation that I just encountered tonight. About an hour ago, I turned on my MacBook Pro and opened Safari, however I found that I could not reach any of my favorite websites. So as a step I turned off my computer and reboot it back again, this time the computer connected to the internet however the pages took about 3 minutes to load. The next step was to turn off my wireless router and cable modem to see of that fixed the issue, then again... no luck. I then decided to return my router to manufacturer setting and then reconfigure it manually, and unfortunately I still had a slow connection in my MacBook Pro. Out of desperation, I swithed to my Bootcamp partition and tried on Windows, and then again I had little connectivity on Windows 7 on my Mac. I returned back to my Mac partition and decided to delete all my wifi settings to see of that could fix the issue. Following that measure I went ahead and send my cable modem a refresh signal. Somehow, in the last two steps my computer suddendly recovered a speedy connection and is working fine now.


So I was wondering, could my MacBook's wifi card be faulty or it was a problem with my wifi router and/or cable modem? I have to mention that I was able to get to the internet on my iPhone albeit very, very slow. After the fix, my iPhone is connecting to the internet at the expected connection speeds...


My router is a Cisco WRT54GS v6.0 and I have a DOCSIS 3.0 UBEE Cable Modem from Comcast.


Thanks for any help on the matter!

    Most likely it was an issue with either your router or modem.  I have had similar issues in the past, and resetting the router or modem (in my case it is the same box) fixed the problem.  I would not suspect the wifi card in the macbook pro since you stated that both the laptop and your iphone saw improved connection speed.


    Good luck...
