ADSL BB-Are you wireless or ethernet?

Pssst

Just changed service providers from VM to O2BB. Anyway I'm having issues with the phone wiring in my house and the bottom line is that when i use a phone in the house,the ADSL line dies.

I initially had th o2 box plugged in upstairs on an extension with a filter but due to problems,i now have a filter in the master socket with one leg to the O2 box and the other phone leg to a DECT base for downstairs phone. There is also a DECT charger only base upstairs.

In this mode all works well.
I'm getting 7.8 DL/1.2UL with a 44.5Db line att DL/ 26Db UL and a s/n margin of 5.5Db so it is likely to hold at that.

Brilliant,but i have to use my lappy wirelessly and i prefer to ethernet it.

I may just find a way of feeding a Cat5 cable for an ethernet point upstairs.

Do you tend to run your home PCs wirelessly or ethernetted to your router?

I run mine wirelessly as I really hate wires. My iMac normally has a power lead plugged into it and that's it.

I prefer a wired network - Gig ethernet cards and switches are now cheap, it's inherently more secure, and there's no possibility that you and your neighbours will be fighting one another for wireless bandwidth. It's got enough bandwidth to run three simultaneous TV streams from a central server to three different rooms in the house without any glitches or dropouts.

Surely you fight for bandwidth BEFORE if gets to your router?
Once your router has the signal, then any device looking for bandwidth must be one of yours....unless your netwrok is unsecured.

I'm sure you've already tried it, but change the filter. If the phone cuts the ADSL when using the master socket, it has to be a filter or external line issue.
When you say master socket, I assume you mean the BT test socket beneath the faceplate-that's what you need to test it on.

There are only a limited number of channels, and hence limited bandwidth, on the wireless side of the router. If your nearby neighbours happen to have chosen channels that coincide with what you use, they will contend, and both will run at less than full speed - but obviously only when both are transmitting at the same time.

Unfortunately the wiring here is a little ad hoc !

I have a master socket but its the early smaller one with no semi faceplate. Hard wired off the inside IDCs are two "legs" ,one going upstairs and the other going elsewhere downstairs. I tried the o2 box on the upstairs leg with a filter and a filter on the downstairs line. No joy.

I have now disconnected the upstairs leg so making the wiring Master socket>hardwired ext to downstairs>filter O2 and DECT base. Now works ok and have 7.5M DL/1.2m UL stable link.

It gives me time to plot a more permanent working strategy !

54mbit wireless for laptops (unless I'm transferring large-ish files), gigabit wired for desktops and the server, 100mit wired for the dreambox and the xbox.

I don't like wireless, but it's more convenient and for just browsing the web there's no real difference.

I'm not disuting what you say but i can't figure out how my router's bandwidth output is affected by my neighbours output when they're not connected.

I know we'd compete for bandwidth before the router but i would have thought that after the router my router will output at either the bandwidth going in or the capacity of the router (which ever is the lower)

I thought if my neighbour and i had both chosen channel 11 for example, then we'd both output as i detailed above. How can his channel choice affect my output?

weegie.geek

A wireless channel only has so much bandwidth. If there are two overlapping networks using the same channel, or overlapping channels, the bandwidth is shared between the networks.

Every residential user contends with other users at the ADSL level, with contention handled in the equipment at the exchange.

In addition, those who operate the LAN in their home wirelessly ~may~ be contending with their near neighbours for bandwidth for the connection between PC and router. For internet use it's a bit academic, as the bandwidth on the ADSL line will be the main constraint. For PC-to-PC traffic on the LAN it may be more relevant.
