Hi all,
I thought it would be as simple as flicking a switch to change from router to bridge mode and plug in my own router, and that couldn’t have been further from the truth :(
My ISP provides a huawei hg8145v5. I ordered a static IP from them as well. They gave me full access to the router to be able to put it in bridge mode. The router I’d like to handle all actual routing is an asus zenwifi xd8.
The setup I’m going for is ISP ONT/Router > Asus Zenwifi XD6 -> TrendNet 10g unmanaged switch -> NAS, PC, server
So in the isp router, I set it to bridge mode and connected it to the wan port of the asus router, then connected LAN 1 of the asus router to my 10g switch. basically just inserting the asus router in the chain that had been working before.
I had no internet at all. Strangely, the asus reports that the internet is connected, but the speed test on the qos section cannot connect whatsoever.
I thought it might have something to do with the static IP, so I tried setting the static IP assigned to me to the WAN IP, used the same subnet mask the isp router had assigned, and set the isp router as the gateway. Same exact thing. Basically everything I tried resulted in either a “connected” status yet no internet, or a “disconnected” status.
I’d really appreciate some help. I really though I’d just change the isp router to bridge mode and I’d be smooth sailing but I’ve basically blown up my network. Also for some reason, the windows network tab is not finding my NAS anymore. I can only connect by typing its local ip or mapping a drive, but I used to be able to go to the network in window explorer and my nas would show up there and I could just access everything I wanted that way. anyway, I’d appreciate any help. i’ve been at this for literally the entire day and am only now reaching out for help. Thanks!
Have you tried contacting either your ISP or the router manufacturer?
I had a similar issue and my ISP mentioned that there was another setting I had to change on my bridged router. I never would have found it without calling them up.
Interesting. I’m dreading that because it seems the only requirements for landing a job at an ISP at mexico is complete ignorance of A) networking and B) the policies of your employer. It’s on my list today but was hoping I would be able to solve it without dealing with them. I already have high enough blood pressure as it is
So if you turn off bridge mode on the ISP router it works? Maybe check the IP and so on that the ISP router gets assigned then.
As a shot in the dark: maybe the fixed IP gets assigned according to the MAC address of the ISP router, in which case you might have to spoof the same MAC on your Asus router.
Another thing might be the ethernet port on the ISP router. I have one that allows bridge mode only on one specific LAN port.
Off the top of my head I’d check - possibly with ISP
- MAC address - does it need to be cloned?
- VLAN - some ISP’s provide internet and other services like ip-tv on different vlans
- PPPoE - Do you need pppoe login credentials on the modem? Or on the Asus?
I would try calling your ISP so see if they see anything on there side. I’ve found that most ISPs are reasonable to work with if your patient
I tried and they were absolutely adamant that they don’t do any support outside their normal configurations. They told me I would need an outside technician to help me. They wouldn’t even tell me anything about whether i’d need to clone the mac address or use a specific vlan or if they supported ppoe, nothing. Fortunately I got it working just hitting mac clone and using automatic ip configuration
I guess I am luckily then
This may be a sizable leap in debugging, but for strange networking issues, I’ll usually start Wireshark and monitor whatever traffic is coming from the ISP’s equipment, looking for clues. A really nice clue would be something like VLAN tagged traffic, which would indicate the ISP requires a certain VLAN ID. Or perhaps you could see if your DHCP requests are being answered or not.
I do recognize that this sort of network sleuthing is as much art as it is science, so your mileage will vary.
Thanks! Yeah I’m actually not totally sure my networking skills are up to snuff. But there is some vlan stuff in the admin interface of the isp’s router. So I would just copy the vlan id over to the correct place in the asus router?
If the ISP router has a VLAN ID configured, there’s a possibility that they strip it before passing through to your equipment, so you wouldn’t need to configure it on your end. So while there’s no guarantee copying the VLAN ID will work, it could still be worth a try.
