No connection after changed router

March 15, 2011 at 02:08:44
Specs: Windows 7

I have changed my router as it was not working very well, although when working my new dell inspirion 1545 was linking to it ok.
I have changed the hub to try to sort out the problem with the internet and all other computers and laptops connect fine (all are older pc's with XP) but the new laptop will not connect - it has windows 7.
It seems to find the hub but will not connect to it - Hub is BT home - What is wrong with it and how do i sort it out? Please can someone help ?
Non technical person ! Please reply simpleton style ! Many thanks.

If the Win7 box connected before, this is probably an IPv6 issue. Win7 ships preferring IPv6, but some older equipment might not support it. Flash your equipment with the latest drivers. You could turn off IP6 in Win7, but it's not a good idea.

Thanks for the reply.
Am sorry not a very technical person at all.
Flash the equipment with the latest drivers ? How do I do this - it is a new computer and I can't download anything if I cannot connect to the internet?
Confused !

I probably would connect the computer directly to the modem to make sure that it is connecting correctly. If it is, then the problem is in the router or hub. If so, you will need to download the latest drivers for them and then connect to each device and "flash" the drivers. If not, then the computer has its own problems that will have to be analyzed.

My win7 box connected to all of my ipv4 network devices no problem right out of the box.

all of the computers are working fine except the laptop.
no connect to modem required
no flashing required
no driver updates required

What we do need to know is if the laptop is connecting wirelessly and is that the issue?

Otherwise it would be great to see the results of an ipconfig /all from the win7 pc

Ok - thanks for replies - as I said not very good at this so please stick with me - the computer connected wirelessly before the hub was changed and will connect when plugged in via the cable.All other pc's are XP connect using wireless.

It will find the hub using wireless but will not actually make the connection to it - I am unable to give error message at this time as I do not have the details with me.

Wireless connections are sometimes a bit like black magic. Its possible your new BT Home hub and your laptop are just incompatible (have seen this a few times). Its also possible the encryption being used is causing a problem (even though both are new devices and probably hub is using wep2). And

I'm presuming that the new hub has a different SSID (ie, the name of the wireless network as you see it on list of available networks) to the one used by previous router? Because if its the same, your laptop will be trying to connect with the old stored credentials and even (especially) if wireless key is the same, windows 7 (unlike xp) knows its a different network and will not connect. If SSID is same & key different, also won't connect - but you would have had same issues with xp machines in that case. In this case you need to remove the stored details (using manage wireless networks) and then reconnect.

Thanks Steve

Will try this as the computer works fine on my other wireless connection at a different location. Must be the compatibility of the new router and windows 7. as the xp computers still work with no problems at all.

Will remove all previous connections and re set it up (not sure of the technical terms) and see if this works if not I shall be back on line asking for more help!
I will let you know one way or the other - thanks for putting it in English though - when you don't know much about computer connections it really helps.
