wifi ok but no ethernet ?
 

i had a superhub 1 and last week ethernet connections all stopped working , so i was sent a superhub 3 and i have connected it and have the same problem , wifi is fine but nothing will connect hardwired . Has anyone any idea why this would be ? i have an engineer coming in 4 days , but is it probable that the problem is in the cabinet outside ? thanks

Re: wifi ok but no ethernet ?
 

Do you have more than one PC/device connected? If it’s just the one it could be a faulty ethernet cable or perhaps the network card within it is faulty.

If you have multiple devices connected by ethernet, it would be really unlikely that they are all faulty. That’s assuming they are not connected via a switch to the Hub?

Re: wifi ok but no ethernet ?
 

no because the cabinet solely deals with the outside internet connection to your house and if there was a problem with it you wouldn't have any internet at all. If wifi is working then there isn't anything wrong with your internet connection and it is a configuration issue with the shub (maybe). This is the first time in the shub's existence (for me) that VM can justify manufacturing it) because the tech coming out isn't going to fix anything per se and just needs to know how to fiddle with the shub settings.

Can you reply to the post above and explain what wired devices are connected to your network and whether or not they are directly connected to the shub or to an access layer switch which is connected to the shub.

Re: wifi ok but no ethernet ?
 

Thanks , i have a number of things ( pc , Amazon box etc ) hard wired directly to the superhub , and non will connect . Virgin tried to run a test over the phone and said they couldnt complete the test . Everything was working last week on the old SH 1 , and all of a sudden whilst i was on the pc , i lost hardwired connections , so they sent me a SH 3 , and still nothing will hardwire .

Can you surf the web via the wifi as you say that's fine?

Re: wifi ok but no ethernet ?
 

ya, is wifi working because you can pick up a signal and connect to the network or can you actually get on the internet? Whether it is a wired or wifi connection if the router is okay but it has lost its internet connection it will tell you you are connected but with "limited" connectivity.

Either way, can you take a look at this post, skip step 1 and go to step 2 and let us know what it says. If you have lost your internet connection in the downstream tab you will only have 1 channel listed instead of 20 or so. Also, colour are the light on the shub and are they flashing or solid?

Re: wifi ok but no ethernet ?
 

Is the WiFi picking up from a VM hotspot? If my BB failed, my laptop, tablet, and phone would connect to WiFi from a neighbours VM hotspot.

Re: wifi ok but no ethernet ?
 

wifi is working on the router. The lights on the ports of the router are 2 fixed green and 1 occasionally flickering green. In router settings diagnostics say something like "port 1 device 100mbs but not getting 100mbs" .if that makes sense ? Thanks

I will try to post screen shot of router status tonight when I'm home.

Re: wifi ok but no ethernet ?
 

Just remembered, I had a similar problem a little while ago. The Wifi was ok but the router couldn't connect to anything else. Had to do a hardware reset. Look for the "button" labelled "reset" and poke something in there to press the button.

Re: wifi ok but no ethernet ?
 

i have amazon box directly wired to router with new cable and it says no ethernet device are connected to router . thanks

Re: wifi ok but no ethernet ?
 

very interesting. Those screenshots show that your internet connection is working perfectly so you haven't got anything to worry about in that regard. All your ports on the switch are gigabit ports so the fact that it is saying stuff is running at less than 100mbits means something is wrong and there is probably no communication at all. Even if you weren't actively using any of the devices the leds on the switch would still be flickering because the switch and the devices talk to each other constantly. Out of interest, have you changed any settings in the router part of the shub over the last week and also configured that new setting on the new shub3? I don't think the shub/switch is at fault because getting a new shub would have fixed the problem and it hasn't.

I don't want to ask you to do a factory reset of the shub just yet because I know what an inconvenience it is to set your ssid's and passwords and stuff up again although it may be necessary to get it out of its bricked status.

Can you turn everything off (shub and pc), disconnect all connected wired devices from the shub including Amazon box and whatever else and only connect 1 pc. Turn the shub on first and give it a few minutes to establish its connection to VM and boot up and then turn your pc on let it get a new ip address from the shub.

When you have done this:

a) does the pc have internet access?
b) what does the network icon on the taskbar indicate
c) do you get the same error message in the shub diagnostics

We need to do this for troubleshooting and go through a process of elimination because something is causing the switch to lockup and I have a funny feeling it could be something to do with the Amazon box. I can remember this happening with the shub1 when you had games consoles and stuff hammering it but this is the first time I have heard of it happening with shub3.

If that doesn't work can you go into the shub's gui and put it into mode mode. When you do this the pc will need to be connected to port 1 on the shub1 because port 1 is the only port which will work and for all intents and purposes the shub will be a modem and not a router which means you will lose your wifi temporarily and the other ports on the switch until you turn it back. When you put it in modem mode the shub will reboot and it may be wise to restart your pc as well because if it works your pc will get a proper new wan ip address. You will need to access the shub's gui on http://192.168.100.1 to turn it back to router mode but if you still experience no connectivity you will have to do a factory reset to get it back into router mode and the wifi up and running again.

I am not au fait with the shub's gui because I have only ever used it in modem mode in conjunction with my own router so without mentioning tabs and buttons can you tell me what settings you configured when you set it up such as dhcp, ip address range, any access control list or firewall settings etc. Basically anything you changed from the default.

Re: wifi ok but no ethernet ?
 

Thanks for your help. I don't want to change anything in the superhub 3 settings just incase I mess it up and loose the wifi . I haven't altered any settings in either of the routers. I will unplug everything and only connect the pc and see if that works. If not , I will wait for the engineer on Monday and let you know what he says thanks

Re: wifi ok but no ethernet ?
 

Ok cool. I have a sneaky suspicion that only having the pc connected will work. Make sure you turn everything off first and then turn the router and pc on one at a time. Everything else can stay turned on, just pull the cables out the back if the shub before you turn it off.

Re: wifi ok but no ethernet ?
 

Your right , pc now works , im still struggling to get the amazon to work , could this be due to a dns server i have on the amazon to enable me to watch kodi ? A very big thanks for you help and patience .

Re: wifi ok but no ethernet ?
 

Simple to find out, try another DNS server.

Re: wifi ok but no ethernet ?
 

Possibly but before you faff around with your amazon box reconnect everything to the shub and make sure it all works properly and then we know it is the amazon box that is causing the problem. When you reconnect stuff you dont have to power down or reboot anything, just plug the cables back in to the shub.

As far as dns goes, one of the flaws of the shub is that you cant set your dns servers so they get handed down to the clients via dhcp, you need your own proper router for that. If you are manually setting the dns server on the amazon box try 8.8.8.8 which is google dns.

Re: wifi ok but no ethernet ?
 

I'm wondering if the new router has assigned a new ip address to the amazon box and I may need to reconfigure the new ip address in the configuration settings. Could this be right? Thanks

Re: wifi ok but no ethernet ?
 

Possibly but the only way that would happen is if you overrode some type of setting from "automatic" to "manual" so you could specify the dns server. If you have to set everything else as well then the gateway will be 192.168.0.1 and the ip address can be 192.168.0.254. If the amazon box is set to receive everything via dhcp, which it will be by default, then you shouldnt have a problem. If you tell me what the name and model number is I'll see if I can find some instructions and what you should do.

Re: wifi ok but no ethernet ?
 

im struggling to get the amazons to connect , it keeps making the hub loose internet connection and im having to use wifi again to connect my pc to the internet . is there a way to resolve this ? thanks

Re: wifi ok but no ethernet ?
 

At least you now know what's causing it.

Did you change the amazon box DNS and does it still cause the problem?

Re: wifi ok but no ethernet ?
 

yes, you can give me the name and model number or at least paste a link to it because I have no idea what an "amazon box" is.

the hub isn't losing the internet connection, if it was non of the wifi connected devices would have internet access. The amazon box is causing the switch (Ethernet ports) to lock up which is preventing network connectivity for wired devices.

Re: wifi ok but no ethernet ?
 

Hence my reply as I've seen it happen before although with another provider and different hub.

Re: wifi ok but no ethernet ?
 

one of the amazons is playing now ok , using the dns settings , i think its one particular box that seems to be a problem . i will look later , as its doing my head in and need a break . thanks

@ General Maximus , you are right its the Amazon fire tv box that is causing the ports to switch off and then i have to use wifi .https://www.amazon.co.uk/Amazon-Fire.../dp/B00UH2O6T2

i have 4 of these boxes , one is fine with the dns , so i dont think its the dns thats a problem , one causes ports to switch off and i havent had time for the other two yet . thanks

Re: wifi ok but no ethernet ?
 

OK go your own way I'll bow out.

Re: wifi ok but no ethernet ?
 

what dns settings? VM's dns server which gets handed down by dhcp to the device or a dns server which you have manually configured? I have had a look at the instructions and they are useless. I am non the wiser as to what options are available in the network settings.

Re: wifi ok but no ethernet ?
 

I wonder if your "amazon box" is sending PAUSE frames repeatedly on the ethernet?

That would cause all traffic through the hub's built-in switch to stop if it supports them.

Someone had a similar issue with a smart TV and documented it here: http://jeffq.com/blog/the-ethernet-pause-frame/

Re: wifi ok but no ethernet ?
 

Its a dns server that i have manually entered , that seems fine as i have had it working and its not switched the hub ports .

Re: wifi ok but no ethernet ?
 

Something is crashing the ethernet, just connect one thing at a time untill the fault comes back

Re: wifi ok but no ethernet ?
 

i think it could be an ethernet cable , i have a couple of splitter boxes for the ethernet cables and it seems to be the cable in the bedroom that wont connect any of the amazon boxes to the internet , would a dodgy cable cause the ports to stop ? as i have had all the boxes working now in different rooms and the ports havent stopped when the amazons where working . thanks

Re: wifi ok but no ethernet ?
 

there are no such thing as splitter boxes and we specifically asked you right at the start how the devices were connected to the shub and whether you was using any switches and you said no, it was a direct connection. That of course didn't make sense when you said you had 4 Amazon fire tv boxes and a pc (plus whatever else) which makes 5 devices going into 4 ports on the shub.

Re: wifi ok but no ethernet ?
 

Could be one of these I suppose: https://www.amazon.co.uk/dp/B072J38J...a-364096147817

Re: wifi ok but no ethernet ?
 

thanks for the link, I have never seen anything like that before and I will never use anything like that, it is cheap ass crap for people who don't have a clue about networking:

I completely understand why something like this would screw up a switch and cause it lock.

Re: wifi ok but no ethernet ?
 

Wouldn't it be simpler and safer just to use a cheap gigabit 5 port switch, for between £15 and £20?

https://smile.amazon.co.uk/Linksys-B...n%3A1036543031

In fact, there are some available for around £12.

(other switches are available...)

Re: wifi ok but no ethernet ?
 

@ General Maximus, I don't use one of those cheap splitters . I am using a tps link 5 port splitter from pc world. I am just asking if a faulty ethernet cable (may be if wires were broken and shorted ) could cause the ports to freeze . I haven't had any problems today. Thanks

Re: wifi ok but no ethernet ?
 

If it is easy enough to swap the ethernet cable, then it’s probably best to try that first. It could be a faulty switch, which is what I’m gathering is being referred to when you say splitter, if so, then it’s cheap enough to get a Gigabit rated switch.

Re: wifi ok but no ethernet ?
 

:banghead: are you sure it's not a TP Link 5 port switch? Can I have a link. A broken cable can definitely cause connectivity issues for the device it is connected to but I can't imagine it killing a switch. If it is a decent quality cable you would be hard pressed to break it tbh, there would an apparent cut in the cable somewhere in it's length or more likely at the termination at one of the ends where the wires go into the plastic bit (which may have come a bit loose). Either way, replacing the cable is relatively inexpensive and it should be easy enough for you to work out which one it is. If the switch is faulty or you need a new one of whatever it is you have got get one of these. Next time you need some new cable(s) or if you want to do everything properly now to save it happening again in the future then replace everything with the appropriate length of these. You can also colour code everything and for example, use a blue cable for your pc, grey for each of the 4 Amazon fire tv boxes and then a black cable for the connection from the switch to the shub. That way when you look at the cables (if you haven't labelled them) you know what each one does.

that is the switch . the cable that i think is faulty is a flat ethernet cable , and when plugged into the switch and the amazon box , the corresponding light on the switch , doesnt light , as if there is no activity , and the amazon box says there is no internet connection . i will test the port on the switch with a new cable . The only thing that was puzzling me is that i know the faulty cable was working in the morning , but hasnt worked since , thanks for all your help , im nearly there now .

Re: wifi ok but no ethernet ?
 

Flat cables are generally unreliable as they cannot be fully twisted.

Many consumer electronics devices only have 100mbps ports - e.g. my Sky Q boxes are all 100mbps, Hive, Hue, etc etc. It's more common than you'd expect.

You can in theory run two 100mbps connections over one cable with a splitter, as each only uses 2 pairs of the 4, with an adaptor at each end, but don't do it, it is bad.
