Wi-Fi can't access certain websites

My home Wi-Fi can't access certain websites and would forever load until it throws up an error state. When I'm connected via ethernet, it works fine, so I know the Wi-Fi has issues. I also want to add that my printer normally prints via Wi-Fi and lately it hasn't been connecting. I'm having to hardwire my printer to my Macbook.

  • The devices I'm using are Macbook and Android phone.
  • This problem started roughly three months ago. No changes have been made to my Wi-Fi (that I know of).
  • I tried changing the DNS. It worked for a day but now the problem continues to exist.
  • I've reset the modem/router.
  • I've tried accessing aforementioned websites on different browsers. Same problem.

It's time to diagnose the connection with the command line.

Try the commands below by replacing www.google.com with a site you wish to visit.  Try it with WiFi, then try it with Ethernet and see what responses you get.

Open Terminal, then cut and paste these lines into it:
nslookup www.google.com
nslookup www.google.com

ping -c 5 www.google.com
tracerout www.google.com

Show us the results.

Open System Preferences.  Select Network.  What do you have for Location.  Take a screenshot and post it here.  You can use preview to blot out your IP address and your network name.
What kind of websites are these? Is it possible that Parental Control settings block access to them? See this site for setting up Parental Control.

I suggest you, to check with alternate wifi router before giving much stress. It's looks like the problem with your router itself which is malfunctioning.

@hdhondt - I don't have parental control on. The websites I'm trying to access are just shopping and gaming guide websites, more specifically at the moment www.katyperrycollections.com.

@serialband - Those commands you gave me are telling me "command not found." First, I tried it with just www.google.com and it accepted the command. Then I replaced www.google.com with one of the sites I'm trying to access which is www.katyperrycollections.com and it's saying "command not found". Bizarre that that one didn't work. (See attached screenshots)

Additional info: I have a Linksys WRT3200ACM router.

@Mitul Prajapati - I kept my old router and switched it out just now, and lo and behold, it seems to have resolved the issue for now! Looks like my current one is just a bad router. I want to wait at least a day to see if this fix is good and I also want to try it with my Wi-Fi printer.
Mitul PrajapatiIT SupervisorCommented:
Sounds Good. Let's see, how it will go.
Rob KnightConsultantCommented:

have you updated the faulty router with the latest firmware?

You need to Hard reset your router and reconfigure it and select the same channel for WIFI and Settings that your old router use.
@Ramin is probably correct. A similar thing happened to me once. After lengthy discussion with my ISP, they finally suggested to reset my modem to factory defaults. Try it, and see if it fixes the problem.
Rob KnightConsultantCommented:
The author has already performed a reset.
There's a difference between reset and factory reset.
Tim LapinComputer Consultant (Desktop analyst)Commented:
Newer routers have more sophisticated - and hence - more complicated options such as traffic shaping, client priority and so on.  I had similar issues with performance until I found a balanced setting for all my devices:
- 2 desktops
- 2 phones
- 2 ebook readers
- 1 tablet
- 1 wireless printer
- 1 TV

It's possible that her old router either had all those options set previously or lacked them altogether and therefore avoided those particular headaches.

Hi everyone. Thank you for all your responses! I don't believe I performed a factory reset; just a "normal" reset. I will try the factory reset tonight. As far as the latest firmware, I'll have to check that later as well.
RaminTechnical AdvisorCommented:
Don't use WIFI to reconfigure the router,  use a LAN cable to connect your router to the PC.

Note: to reconfigure a router you need to know or write down some values from old configuration.
Kat DoneganUX/UI DesignerAuthor Commented:
After a couple days, my connection is still stable and no longer limiting me on which websites will load. My Wi-Fi printer also stays consistently connected! It was definitely the router issue. Thank you all again for your help!
