BUGGA! SOLVED! Internet Connection Problem, ?

[astronobob]

Hi all, Ive run out of options,

Basically - New Telstra Modem (Cable) as thought other modem was faulty but apparently maybe not ?
Very very new PC, latest Gigabyte motherboard with latest I7 processor, windows 7, windows essentials. 2 x 250gig SState drives

Problem: Hook Lappy to Ethernet = Internet
Hook PC to same Ethernet = No Internet
Take PC to PC DR = gets internet, totally no issues, no bugs, not a single piece of malware or any issue, zilch, PC perfect in every way !
At home: Modem, cable, ports perfect in every way.
Modem signal reaching PC Ethernet Port with both lights working. No connection to internet ?
Plug Ethernet to Lappy - no worries, internet connection !

When New Modem arrived, a week ago, I set it up, connected the PC via Ethernet, got internet no worries, - next night, no internet and since then no internet, yet PC is perfect, and Modem perfect & is sending signal to Ethernet port - No connection ? Take PC to Dr, gets internet no worries,,,

What the heck is going on ?? Finding this very very strange ??

:shrug: :rolleyes: :screwy:

[g__day]

Open a Command prompt and type

ipconfig /all

And share what your details are - particularly IPv4 address, Subnet mask, default gateway, DHCP server, and your likely 3 DNS servers

Is the Telestra Modem a combination modem / router? If so post a picture of it and what ports you have connected cables too. If it stored the Lappy MAC address somewhere it might be puzzled when you hook up a device with a different MAC address on the same port. Could be many other things, need more data to analyse the fault.

Thanx Mathew, sounds promising - will go further on this tomoro eve, I am hitting the pillow for the night now mate :thanx:

[astronobob]

Here some pics Mathew, Its a Netgear Modem !

The Ethernet port light is Not on as I didn't have it plugged into PC at the time !

Im not sure how to even open a Command prompt, Lol, where/how do i get one of them open - -

I have just now restored factory setting on modem, have connected the lappy with wireless only - works fine ! Plucking up couraged to try the PC through the No 1 Ethernet Port now - nerves, Lol

[astronobob]

HEYY - WOOHOOO ! Working :thumbsup:

Just hope it lasts this time ? Like you mentioned, may or most likely was conflicting with two units using the same port - who'd of thought, not this duck :rolleyes:

Mmmm, puutas, mind boggling - give a broken down Ford anyday :lol:


Thanx for jigging some action Mathew, appreciate it very much :thumbsup:

Breathing a little easier now, but prob have another heart flutter when i power up tomoro night ? ? Lol

Keep an eye on this space :question: touch wood ;)

Kind Rgrds
Bob :thumbsup:

[astronobob]

Knew was to good to be true, ,

Try internet again today, No GO - reset everything - NO Go,

Only my PC connected to Ethernet port

Both my & Missus's Lappy's getting wireless tho

Sooooo FrusssTrating - I give up soon i tell ya - just dont get this *#!**@

[scagman]

Hi Bob,

Have you tried opening the "Network and Sharing Center" (Start menu>control panel)
That will show a basic diagram showing pc---network--internet

If you dont have internet access you will have a cross thru the network--x--internet.

Try clicking on the 'x' and see if windows can fix the problem. Sometimes it can, depending on the problem.

Hope this helps.

Cheers

[BeanerSA]

How old is the PC? Network ports can fail over time.

[astronobob]

Yes John, I have tried both IE & Chrome to do a Diagnose of the internet connection with no results,, ,,, Tho I havent started by clicking on that cross you mention, I do have a cross there tho, so ill try it from there, but will probably be the same diagnostic tool, just a different way of opening I guess, I also have an 'exclamation mark' down on the taskbar icon too, ?

Funny tho, if I switch the ethernet cable and plug into lappy after turning the lappy 'wireless of - I get internet through the ethernet on lappy no probs ?

Somthing wrong on PC somewhere, ??

[astronobob]

Yah thanx Paul, yeah not even 4 months old - read 1st post for description of PC if need more info :thumbsup:

[g__day]

Bob,

That really looks like a combination broadband modem, Router, and 4 port switch to me. Post a picture of the model / part number if you can,

As a hint always try and plug devices into the same yellow ports 1 -> 4 (not the red uplink port next to the round black broadband cable).

You open a command prompt by click the home Start icon, selecting under all programs that search box, and typing cmd. this will open a DOS like shell, then you type
ipconfig /all

or

ipconfig /all > c:/networkstats.txt

which will create the file networkstats.txt as a text file.

then type exit to close the DOS command shell.

, then you write down and share the details

[astronobob]

Cheers Mathew, ,

Telstra ph tech support had me type in command prompt; NCPA.CPL which opened a 'local area connection' network logo thingo - then right click and click on 'dissable. - let it flicker - & right click again and 'enable'

This made the connection work, but only once. it is like a manual switch, when I close down the internet, I cant get it again unless I do this manual switch again !

The Tech says that it is most likely a software-program issue/fault with the PC / network card or Ethernet port or a driver or something else similar ??

Looks like the PC is going back to the puuter builder work-shop tomoro (Sat) morn or Monday ?

[astronobob]

Found the 'Error' 651, - working on it ?
Have googled it and came up with some remedies to try
Ahhhh,, there is small glimmer of light at the end of the tunnel yet !

[acropolite]

Bob, we tackle these problems all the time at work. The problem is most likely with your router or could be caused by smartphone or tablet connections if you use those.

The next time you can't get a connection turn off every device but for one PC, then see if the problem still exists.

Assuming the internet authentication is done on the router, browse the gateway IP from your web browser, most routers have a status area which should tell you whether the router is connected and authenticated.

Mobile devices i.e. iPad, IPhone, and Android devices can be notoriously badly behaved on wifi, I've lost track of the number of times we've been called to check faulty cabling only to find that a smartphone or tablet is bringing down the network.

The best remedy for that is to check the router's settings and statically assign dhcp addresses against each device, that will assure you have no IP address conflicts. I've found at least 5 sites where doing that stopped the network issues, once the Tablets and phones had static assignments the problems were solved.

The phone/tablet issue is caused by the device assuming it has the same IP lease when the router has re-assigned the lease to another device and two devices end up with the same IP, it's a well documented problem. Good quality switches have ability to continue working with IP address conflicts, but the average home and budget business gear simply falls in a heap.

[astronobob]

Thanx very much Phil ..

Ill do a power cycle and turn off both my & missus's lappy's, my iPhone and her Samsung andriod phone & restart my PC check for net connection, if so, will do a restart and see if connects twice in a row - this should/could confirm modem issue and conflicking then ?

will reply later tonight, still have some other chores to do, Lol

[astronobob]

I have also let a friend know you thoughts and related info, he has more of a clue than I, so hope can get him here to run through (statically assigning dhcp addresses against each device) one day soon if this is the case :thumbsup:

Really appreciate your time and input, Phil & Mathew & John

[astronobob]

Mmmm, found this (link below) via googling (statically assign dhcp addresses) -

http://www.howtogeek.com/howto/19249/how-to-assign-a-static-ip-address-in-xp-vista-or-windows-7/

havent read it yet, but me and mate will 'mull' over it when time allows ?
a day or two, LOl .

Cheers !

[g__day]

The brand and model of the gear is?

Post the IP stack configuration report too please!

[astronobob]

PMéd Mathew

Also have these attached screen snips if any use ?

I have manually connected to net at the moment, but the problem is - I have to manually connect each & every time when I restart the PC - I guess a could leave it sleep mode until the problem is resolved - maybe it needs a good sleep :lol:

[dannat]

Bob see my pic, right click on your connection [ethernet in my case], then select properties [Ip4} then select properties again -you want to see the tick dots in the automatic DNS address boxes, if you have a series of numbers in the bottom DNS box untick it & select automatic -we are gtting a lot of annoying ware changing this setting at work -game sites also a problem

[astronobob]

Thanx Daniel, but guess what, Ive just been through this with the PC Bloke over the phone and he commanded me the 'magic numbers, etc some were missing, and was a bunch of 0 0 's in which shouldnt have been there in one place - any way we did all this and The Problem Remains

Anyway, he will be dropping in here personally Weds/Thurs, even he is a bit confused as to why this is happening ?
I might just try the Áuto IP now as we didnt do that-a-way, as he put in some generic values, guess he used them as he know the PC, tho, never know with out trying huh :thumbsup:

Fee of charge id say as Ive had this issue since he upgraded the whole shebang a couple of months back

Cheers Daniel :thumbsup:

[GrampianStars]

First option is go get and use a NEW cat 5 cable ! :rolleyes:
Cables are the "Weakest Link" :lol:
use a cable tester

[astronobob]

Point taken Rob, thanx :thumbsup:
I am dropping into J-Car tomoro anyway - so, may as well cover all bases - on this note tho - whenever I plug the cat10 ethernet cable to my lappy, it never fails :question:

2nd thoughts there's a brand new cable that came with the modem, two I think, tho only a meter or two long, I can wheel the puuta desk over and try all the same before another purchase :thumbsup:

Good thoughts mate - appreaciated :thumbsup:

[astronobob]

Weird stuff going on here Daniel, did the Auto address - still no go mate, , Grrr, gone over this toooo many times - - leaving it for the Tech visit me thinks :thanx:

[astronobob]

mmm Problem Remains - had the PC Tech guy here for near an hour, no go, he says it is a Windows Problem and for me to get around it by 'manually switching, as in, disable network then enable network' bugga, have to do this on every start-up.. could leave the PC in 'sleep mode' most of the time.

Weirdest thing was, tech guy found that when after 'manual switching' to enable, and getting Internet, Windows stated that it Cannot see the DNServer ? BUT IT GETS WEIRDER - When Windows Does see the DNServer, PC can Not get the Internet ? ? ? WTF

Anywho, Other suggestion Option was try upgrading to Win10 ? ?

[g__day]

Got a friend local or neighbour with a PC or laptop to pop in and try their machine on your router to see if it gets internet connectivity, then consider testing your PC at their place. That would isolate if the problem is with your PC, your router or both!

Its unlikely but on your PC the software part of the IP stack may have somehow got corrupted. The easiest fix for this is to from Windows - have a techie delete your network device then re-instal it and its drivers. That would reset the software part of the IP stack.

Alternately if its a desktop with a spare PCI card slot then just add another network card - they cost around $45, Install this, let Windows detect it and install the drivers and then simply switch the cable to this and see if the problem goes away. That would fix the problem if its a failing network port with a corrupt IP hardware stack.

[astronobob]

Awesome Thanx Mathew, makes a lot of sense to try the PC elsewhere ect.

This Tech guy did re-install a driver in for the network device, but not the whole network device, the new/reinstalled driver didn't help any, actually it wasn't easy to find the right one, but I guess he wasn't able to spend too much time with finding a complete device re-install, but I reckon he should have tried, maybe he didnt think on it ?

Ill call him and have another chat, also about trying a new network card ?
I can also take PC to a friends and see what happens there, and maybe visa-versa ? My Lappy does Not have a problem with the same ethernet connection tho, works every time ?
Anyway, more experimenting to do from your advice !
Appreciate your input again Mathew :thumbsup:

[g__day]

No worries.

Techies should know to look for driver files first in c:\windows\inf and then in c:\windows\drivers\system32 most drivers will already be there!

[astronobob]

Ok,

Im still working on this and I'm finding areas which are questionable ? Here are two 'screen snips' and I have 'yellow highlighted' some interesting findings that may have relevance ? Im not sure but thought to post incase there is an issue noticeable ? ?

Pic 1)
Question A: On Left - Whats with the 'Lease Obtained/Expired 1 hr - is this normal or could it be a regitering setting when connect each time and there-fore lasting only 1hr - so when I shut down, time has expired ???
I got no idea ?? Just asking ...

Question B: On Right - Should I be needing a a connection with IPv6 ? I know I have connection with IPv4, but is this correct, maybe I need IPv6 and not IPv4 ? Or , do I need both ? ?


Pic 2
Straight forward question - Do I need a Network Address Value ? If So - Wheres one can I get ? ?

:thanx:

[astronobob]

A mate of mine found the issue, was part of Apple Adobe Photoshop suite - possibly with Dreamweaver at a stab ?

Anywho - here a couple of snips where to correct it -> In the Task manager -> Services -> Program called 'Bonjour Service' was running, which was causing the issue :thumbsup:

My mate has 'connections' online input etc to with his work field, he also mentioned a quite of number of peeps are having the same issue, Re: Internet not starting up ! I'm not sure if the above 'fix' is relevant for all others tho, but worth making a note of it I guess ?

BTW, My Adobe PShop, Illustrator & Dreamweaver are an older 'disc' version and namely PS3 collection - I guess the issue, if relevant, could be in other similar versions, eg: PS2 Ps4 Ps5 maybe ?

I also mention my appreciation to all who placed input into this thread as you all inevitably help create a path of - try this,, try that, which lead me to here :thumbsup:
Cheers all, im in your dept :thumbsup:

[speach]

Are you using M/S internet explorer? If so try this open IE and internet options open connections then open LAN settings and see if the proxy server box is ticked, if it is un-tick it and see if that makes a difference. Mine magically ticks it's self and then I get nothing not a thing!!!

[astronobob]

Hey Thanx Simon, have been through that mate :thumbsup:
Ref: Post 20
My last post above yours also - Re: Problem fixed :thumbsup: apparently an Adobe Prog Hick-up - seems ok now, so far - touch wood, tho maybe adobe might switch it ON at some time in the future - who knows, but atleast I know how to correct it again :thumbsup:
