Strong Internet Connection but Page Won't Load

trailblazrr · 05-28-2015, 10:54 AM

Hi all - Hope everything is going well!

All of a sudden: Strong Wifi connectivity but no pages will load!

I would try pinging but apparently I don't know the proper syntax for Ubuntu 14.04.

I also tried restarting the modem and router.

Any suggestions??? Thanx4Help..

Do other network or wifi devices work? Can you access the router's Web configuration page? A strong wireless signal is good but does not indicate your broadband service is working. Check the status lights on the modem and router to make sure everything is working. If you can log into router it should have a status page that shows if it is connected to the Internet.

Well I believe the router is malfunctioning in some way because the indicator is showing red mostly instead of green,

so I have my computer connected directly to the modem via wire and mostly everything is working like that

but still sometimes pages will not load and I will have to wait a few minutes or perform seemingly insignificant clicks on the screen to get it to perform again.

So no wifi right now unless I can troubleshoot both problems. Guess there's a problem with the router and the modem??

Try this:

Code:

sudo su
cat > /etc/resolv.conf << "EOF"
nameserver 8.8.8.8
nameserver 8.8.4.4
EOF
chattr +i /etc/resolv.conf
exit

I think your router's DNS is faulty; the above commands set your system to use Google's DNS.

OK, to stop NetworkManager over-writing resolv.conf, edit the file at /etc/NetworkManager/NetworkManager.conf and add this line to the [main] section:

Code:

dns=none

/etc/resolv.conf might be a broken symlink that you will need to remove after doing that. Then, just create a new /etc/resolv.conf file using the heredocument method above (without trying `chattr +i`) or simply use any text editor (as root); the file should contain these two lines:

Code:

nameserver 8.8.8.8
nameserver 8.8.4.4

As I said, these are Google's DNS servers; if you prefer a more anonymous solution try one of these:

What type of broadband are you using i.e cable, DSL etc.

No DNS could be a symptom versus the problem. Knowing what lights are green vs red might help diagnose the problem. Sometimes working sometimes not could be a caused by a bad MODEM or low signal strength.

check your router's DNS configuration. If you don't have a static IP but DHCP from your broadband provider there should be at least one server entry (sometimes two) for DNS server. Check if you can ping it from your machine. If this works, see if it actually is a DNS server, e.g. by using

Code:

nslookup google.com <IP address of DNS server>
