Chromebooks don’t come with a lot of tools for troubleshooting Internet problems. It can be hard to tell if a connection problem is with the Chromebook or the network. These steps will help you find out what’s wrong with your Internet connection and how to fix it. You’ll see that Chromebooks have a few hidden diagnostic features that can help you find network problems.
When trying to figure out network problems its always best to start with the PC or Chromebook that’s having the problem and work your way outwards to the Internet. The following steps will walk you through the process and show you some Chromebook features you probably didn’t know about along the way.
The first step is always to try another website. If you can connect to other websites then the problem is with the website and there isn’t much you can do about it except wait for them to fix the problem.
Cabling and WiFi Issues
The next thing to do is always to check the physical connections. If you are using Ethernet and don’t see any flashing lights on the Chromebook’s Ethernet port, then you should check the ports and try another Ethernet cable. If using WiFi and you don’t see the Wifi icon in the icon tray (bottom right corner) then you need to double-check your configuration; you probably got the wrong network name, security, or password. (Make sure you haven’t turned off the WiFi -on mine it’s <Fn>F11 that will enable/disable WiFi, yours might be a switch or another key combination.)
Home Network Problems
1Assuming you’ve done all that and still can’t connect you should check to make sure your Chromebook got an IP address from your router. To check its IP address, open up the settings menu like you did above, click on the “Connected to” line, and click on the (i) icon in the lower right corner. The IP address will pop up. If you haven’t got an IP address then you are not connecting to your home router so you need to check your home network. Other devices in your home are probably having the same problem.
2The next step is to make sure that the Chromebook knows that the home router is the way out to the Internet. Now we get into some of the hidden features of Chromebooks. Press <Alt><Ctl>T to get to CROme SHell (crosh) which is the Chrome operating system. Then type route -n
crosh> route -n /0 Kernel IP routing table /1 Destination Gateway Genmask Flags Metric Ref /2 0.0.0.0 192.168.0.1 0.0.0.0 UG 1 0 /3 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0
You should see a destination of 0.0.0.0 with a Gateway. Your gateway will probably be 192.168.0.1 like mine but may be different. The gateway is your home router and the Chromebook must be able to reach it to get to the Internet. If you don’t see a default gateway then your router is mis-configured.
3Make sure that the Chromebook can reach the gateway by typing ping 192.168.0.1 (or whatever your gateway address was).
crosh> ping 192.168.0.1 pid: F98F12B9C4ED720D657F2730BE221B1F PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data. 64 bytes from 192.168.0.1: icmp_req=1 ttl=64 time=7.62 ms 64 bytes from 192.168.0.1: icmp_req=2 ttl=64 time=4.48 ms 64 bytes from 192.168.0.1: icmp_req=3 ttl=64 time=14.0 ms
[sam id=29 codes=’true’]
Press <Ctrl>C to stop the screen from scrolling after you see a few lines. Your output should be something like that above. The times should be below 20ms. If you can’t reach the gateway, then your problem is with your network.
Service Provider Problems
Now let’s see if we can get past the home router and off to the Internet In the crosh tab, type tracepath 22.214.171.124.
crosh> tracepath 126.96.36.199 pid: 73A2AA457E525361874DCE460D6CBE9C 1: 192.168.0.25 0.160ms pmtu 1500 1: vlan1.phub.net.cable.rogers.com 4.762ms 1: vlan1.phub.net.cable.rogers.com 8.855ms 2: no reply 3: 188.8.131.52 285.458ms 4: 184.108.40.206 148.265ms
You should see a bunch of names and IP addresses that are not from your home (192.168.x.y) like the 220.127.116.11 above. If you see that and still can’t get to your website then your Chromebook and home network are both fine. Either the site is down or there’s a problem with your Internet Service Provider.
