Im pulling my hair out

Have just built my Mrs a small PC for a business she has recently set up and she is currently set up an "office" in our dining room.

The house broadband (BT Infinity) comes in the study - into a BT HH5 - connection out into an 8 port switch and one outlet from the switch goes to a Homeplug (3 synced)

One Homeplug goes to the lounge and feeds a Media Streamer and BT Vision Box

The second homeplug goes to the Dining Room (Mrs' "Office")

I built the PC in my study - hooked it up to the HH5 and no problem with home network / internet access

I take it into the Dining Room and plug into the Homeplug and nothing apart from a "Local Area Connection Doesn't Have a Valid IP Configuration" message

Back into the Study - works fine in the HH5, but same error if i plug into the switch

I have noticed that i get different IP addresses if I use the HH5 or Switch / Homeplug and sure (although i may be wrong) this is the problem ?

Switch / Homeplug on the left and HH5 Connection on the right

Any ideas on how to resolve this please ?

Cheers :)
 
The IP on the left is the standard IP the network card will give itself when it can't get one from the DHCP server/router.

Have you tried another pc/laptop on the switch/homeplug? Is the homeplug synced with the one from the HH5?
 
Hi

The three Homeplugs are synced and my Mrs old laptop works fine when plugged i, just the new PC :(
 
Looks like the homeplugs aren't syncing properly

The Ip on the left means it can't find your dhcp server.
Try the plugs in the same room. Homeplugs are flakey at best
 
Thank you

I can try - but odd that into the back of HH5 is OK and anything behind the switch doesnt work ?

And as above - my Mrs' laptop into the same home hub works, just not the new PC
 
Try...

Router to switch to pc. Should work fine. Remove the homeplugs to see if that's where the issue lies.
 
Right, I ripped everything back to :

Interweb in => HH5 => Switch => HomePlugs => PC

Nope

Then realised I had a fourth HomePlug so set up

Interweb in => HH5 => Switch => HomePlug 1 => PC
.........................................=> HomePlug 2 => BT Vision / Streamer

Nope

So, right back to basics and

Interweb in => HH5 => => HomePlug 1 => PC
...............................=> HomePlug 2 => BT Vision / Streamer

And it works but interweb speeds are shocking :/

I think im gonna get a wireless dongle and if that doesnt improve it a 30m length of CAT6 and no-nails it up to the ceiling and across the hall wall between her PC and the HH5 :P

Thanks for the advice :)
 
And as above - my Mrs' laptop into the same home hub works, just not the new PC

So the laptop (Set to DHCP i assume?) in the same homeplug is picking up an address and connecting?

Have you tried setting up the pc with a static address, ie - replicate the right window above?
 
Right, I ripped everything back to :

*snip*

You need to remove the homeplugs from the equation -

Does the pc pick up an address connected directly to the router?

Does the pc pick up an address when connected directly to the switch (the OP says you have issue here)?
 
Direct to the router is fine - direct to the switch is doesn't pick up an address

Ive tried a manual / static IP and that doesnt appear to work either.

Just for clarity:

Ive also got a wireless dongle and 20m cable coming so will probably use one / both of those when they turn up :P

Thanks all
 
REMOVE THE HOMEPLUGS FROM THE EQUATION.

Test... Router to switch to newpc.

...


Your diagrams make no sense, the homeplugs aren't connected up to anything else?


...


After doing the first test. Try with all 4 homeplugs in one room.

Go from router to Homeplug1. Then plug in all the other homeplugs to power sockets in that same room. Now test each one at a time via laptop Ethernet. They may not be sync'd up properly.

...

Help us help you


Nb. Directly connected to the switch and nothing else (no router) won't give you an ip, it's not meant to. The switch has no dhcp server.
