No internet connection when connected to router

Topic

New Reply

Hi Guys,

I’m using a wireless broadband dongle plugged into my Draytek Vigor 2820n router (I’m unable to get landline broadband) and this has worked well for the last few years.

However, I’ve started to get no internet connection so swapped the router for an identical spare thinking it was a router problem, but the replacement router exhibits the same problem – no internet connection. I then tried plugging the dongle directly into my PC running Win 7 (64bit) and I can now access the internet, but as soon as I switch on my router and it has initialised, my internet connection drops out ! I thought that maybe I had a problem with the PC but I have also tried the above scenario with a laptop with identical results. I’ve also tried two dongles just to make sure that it isn’t a problem with the dongle but no luck. I’ve tried resetting my network settings but nothing I have tried has worked.

Do any of you gurus have any idea of what the problem may be ?

Any help GREATLY appreciated.

Graham

You need to troubleshoot the issue from your PC as it seems it’s not the hardware.
When you have no internet.
1. Start > Run, ping google.com
2. Log onto the router and see if you can ping google.com

Hi Paul,

Many thanks for the reply. With the dongle plugged into my PC, as soon as I switch my router on it disconnects from the internet so I’m unable to ping google.com. I can however do this once the router is switched off. This is what I get with the router switched on…

I’m not sure it’s a problem with the PC as this happens with my laptop as well.

If you can a) ping the router successfully from the PC (the router’s User Guide shows it should be 192.168.1.1) and b) connect to the internet using the 3G dongle (USB modem) plugged into the PC directly then doesn’t that suggest the problem may be the configuration of the USB port on the router when the 3G dongle is plugged into it?

As you’ve been using it OK in the past then it’s obvious the 3G dongle is a compatible model.

The User Guide suggests the 3G dongle should show as WAN2 in the router’s Online Status (see pages 44 and 50), i.e. it should show the connection to the internet. Have you accidentally disabled WAN2? More importantly, is WAN2 set to 3G USB Modem instead of Ethernet? (See page 51)

Have you carried out a recent firmware update to the router or carried out a factory reset and subsequently wiped out any required settings for the 3G USB Modem in WAN2? (E.g. dial string or username/password combo)

Hope this helps…

Hi Rick,

Thanks for the reply. I can ping the router from the PC but can’t connect to the internet with the dongle plugged nto the PC and with the router switched on (nothing plugged into the router USB port). These are some of the screenshots…

he last image shows WAN 2 as disconnected presumably because the dongle is not plugged in ?

Screen shot 1 shows that the modem initialization string has been overwritten by the APN name.

What does System Status show for WAN2 when the 3G USB dongle is plugged into the router?

(I’ve no idea whether the settings for WAN2 are correct but at least the fields aren’t all blank, e.g. following a factory reset. I guess you don’t need to use a username/password.)

Hi Rick,

I backed up the config for the router prior to doing an update of the firmware in the hope that it was a firmware issue, but alas, no joy, so I guess the settings are OK ?

With dongle plugged into the router this is what it shows…

At what point did you do the firmware update? Before or after the problem began?

After the firmware update, did you ensure the WAN2 interface was (re)set to 3G USB Modem instead of Ethernet?

Hi,

I did the firmware update after I started having problems as I thought that that may have been the problem. The WAN 2 setting was set at 3G modem as before.

Run a Command Prompt as an admin by going Start – type cmd – right click on cmd – select Run as administrator – accept the UAC then enter –

netsh winsock reset catalog

netsh int ip reset resetlog.txt

ipconfig /release

ipconfig /renew

shutdown /r /t 00

And see if it connects after – it sounds like an IP address conflict.

You need to have an Ethernet cable plugged in for it to renew the IP address for the LAN.

Hi Sudo,

Thanks for the reply. Unfortunately, even after doing the above, I still get no internet connection when I switch the router on with the dongle plugged into the PC !!

Can you repeat those commands with the dongle plugged in and the router switched on.

Notwithstanding Rick’s help, can you open a command prompt and enter ipconfig /all

Right click in the text area – click on Select all and press enter – right click in the reply box and select Paste

Enter exit in the command window to close the cmd prompt.

Hi,

I tried the above commands but this time with the router switched on but alas the result is still the same. The ipconfig /all command gives the following…

Your screenshots show you don’t have any WAN connection/external IP on WAN2, i.e. the router’s hardware interface used by the 3G USB dongle… hence no internet.

(Your screenshots also appear to show you aren’t at the latest firmware update (3.3.7.8). Perhaps the newest firmware update was a re-issue after reported problems with 3.3.7.5? I have no idea.)

Your problem appears to be with your 3G USB modem/router interface – i.e. the USB port’s configuration in the router’s OS. Have you tried Draytek email support or in the Draytek support forum (if not answered by a Draytek Knowledgebase article)?

Hope this helps…

Hi,

Not sure about the firmware as I downloded it a few days ago but will recheck their website in case they had an older firmware listed.
Yes, it seems like an interface issue but this happens on a spare router as well (same model) so unless they have both gone bad with an identical interface problem I’m at a loss as to what it can be. I haven’t tried Draytek support as yet as I’m not totally convinced that it is a router hardware problem – but I could be wrong.

A good point, well made. So the ‘spare’ router is using a different firmware version?

If so then then surely the only common item is the 3G USB Dongle (and your ISP’s SIM). Any recent changes there (even though it works when plugged in directly to PC and laptop)? Do you have a smartphone with a data-enabled SIM connected to the same provider?

Hope this helps…

Hi Rick,

I think the other router had the latest firmware update applied, but I’ve just updated the firmware on this router with the same reults :huh: I have another identical dongle and will swap this out to see if it helps.

Hi,

Just tried with another identical dongle and with the same results.

You seem to have a few Ethernets with assigned IP addresses.

Can you do other ipconfig /alls with just the router switched on and dongle unplugged and another with just the dongle plugged in and the router switched off.

I’m going to have to shoot off for a while, but if Paul T picks up your thread, he should be able to unravel those for you.

Hi,

I’ll post the ipconfig /all results shortly. No problems about having to shoot off – I’m just glad of everyone’s input.

Many Thanks.

It seems to me you have a wired connection to the router that takes precedence over your USB dongle, so your PC correctly finds no internet when the router is on. Unplug the Ethernet should fix that.

Your real problem is the router is not initialising the USB dongle to obtain internet access.
Are you able to see the USB dongle settings when it’s connected to the PC? You should have the router set the same.

cheers, Paul

Hi Paul,

Yes, I have a wired connection to the router from the PC as it always has been, with the dongle plugged into the USB port on the router. This has worked fine for several years. But over the last few weks I’ve found that I can no longer get internet acces doing it this way and I’ve had to plug the dongle into the PC to get internet access. This is OK, but I can’t use the router as the internet connection drops out as soon as I switch on the router!

Not sure about the router not initialising the USB dongle though as this happens with my spare router as well (same model) – unless by some fluke they both have the same problem. What’s puzzling me is that I can get internet access with the dongle plugged into my PC, but as soon as I switch the routerv on I then lose access.

Graham

but as soon as I switch the router on I then lose access.

This is because Windows prefers the Ethernet connection over USB. Remove the Ethernet cable and all should be well.

It is definitely the router / dongle that is the issue. Are you able to get the dongle settings from the PC to mirror on the router?

cheers, Paul

Hi Paul, Sudo & Rick,

I just plugged in an old dongle I had lying around and surprise surprise, everything is now working – how strange is that ??? I’m just wondering whether this was in part due to an aborted Windows 10 upgrade ?

Really, really odd.

Any way, very many thanks to all for your kind help it’s really appreciated.

All the best.

With the dongle plugged into the router, log into the router and disable the WPA/WPA2-PSK security then reboot the computer.

Is it using AES or TKIP ?

Whether it connects or not, log back into the router and re-enable it.

Reply | Quote

Hi,

Tried the above and still the same problem. The encryption is TKIP for WPA/AES for WPA2

I’d buy a new router if I thought it would cure the problem but as it’s happening with two identical routers, I’m not convinced it would be money well spent :confused:

Hi Paul,
Yes, if I disconect the ethernet cable then I can get internet access with the dongle in the PC but that means that I no longer have any wifi for my laptop/tablet etc. which is what I had originally until this problem reared it’s head.

I’m not sure how to find the dongle setings on the PC. In Device Manager the dongle shows as follows…

45161-2016.08.02_21h24m44s_001_

But doesn’t show when plugged into the router !!

Graham – I’m more than happy to be proven wrong but I still think it’s misconfiguration of the router’s WAN2 interface.

In your first screenshot (post #5) there’s no APN name showing. Your router recognises that the USB dongle is using 3G (and initialises the hardware – the Modem Initial String) but other than that it’s pretty dumb. I understand that it may not need a username/password combo but surely the SIM needs the name of the carrier’s APN to know which carrier to connect to?

I think that’s why the 3G USB dongle works fine in your PC and laptop… because the connection software provides the correct APN. I also think this explains why you have the same issue with both routers, even if you change dongle… the SIM isn’t being given the right carrier APN.

Hope this helps…

I guess an easy way to check is to compare your first 3 screenshots in post #5 with what they look like now.

Anyway, glad to hear that it’s all working now.

Hi Rick,

There are a few differences between the various screenshots …

Just pleased that it’s now working.

Thanks again for all your help.

The WAN > Internet Access screenshot showing WAN2’s APN setting is the important one.

Hi Rick,

Yes, I hadn’t really appreciated the difference. The dongle came with scant generic information and I had to get the APN from a website.

Just a guess, but you may have two DHCP servers running. When the router initializes it could be assigning the same IP on the local network to two different devices. You can confirm this by disabling DHCP on the router and test again. If this is in fact what is happening, change the configuration of the router to start assigning DHCP addresses at 192.168.1.100

Hi Steve,

Thanks for the info. Fortunately I’ve now managed to resolve the problem by using an old dongle which ‘Three’ gave me when I first had a contract with them.
