Hi Hoover
You have several problems here, the first is that you can't use a wireless phone and a wireless broadband system in the same house (others will disagree) the 2.4gHz signal is very sensitive in that it will stay connected wireless wise, but all data throughput will cease. are you using a laptop or a pc? if it's a laptop, connect it direct to your router with a patch lead and try your net speed using
Speedtest.net - The Global Broadband Speed Test. (I am assuming that you have the wireless router connected through a microfilter into the master socket) when you have done this try to connect wirelessly to the router and compare the speed. If you get good speed through the patch lead and poor speed through the wireless it is the router at fault, or there is interference. Here is a list of things that I know from personal experience will interfere with a wireless internet connection.
wireless:
phones, alarms, baby alarms, cameras, remote controls for tv's, gates etc video and tv wireless systems, microwave ovens (yes they use 2.4 gHz magnetron!)
2.4gHz wireless signals travel in straight lines and will not go through brick walls, they will go through wood if it is dry, but with losses. they will go through plasterboard, but not if it is foil backed, they will go through K glass, but will lose about 30% signal strength. The signal will bounce round corners( actually it scatters rather than reflects, with large losses) but by and large the straight line rule is absolute. the problems occur also when your neighbours use any of this equipment, especially any neighbours across the road from you! In short, after many years of experience I now advise people NOT to use wireless systems inside as they are unreliable and slow. the manufacturers will not tell you this of course, and if you are using a laptop or Pc in the same room as the router you will probably have few problems apart from interference. The problem of slow speed stems from the fact that every time you connect to a wireless router the first thing the router does is test the connection, if it gets error free transmit and recieve, it will operate at full speed, if there are errors it will default down to the next slowest speed and try again, and it will keep doing this till it gets an error free connection, or runs out of slower speeds! The "bar chart" you see in your wireless connection properties is the wireless signal strength, it is only a very rough indicator of the actual data throughput that the connection will deliver. A recent BBC news article stated that "wireless connections can run up to 30% slower than wired" Not only could I have told them this years ago (but no one would listen) In my experience 30% is conservative.
You will be able to log into your router by putting the local ip address in to your browser address bar, this will be something like 192.168.1.1 (could end .0.1 or .2.1) it should tell you this in the router manual, unless you know the pasword for the router you will need the default password , again from the manual but try admin for the username/ password
As for youe phones, disconnect everything then go round the house and check each phone point seperately with a known good phone. If all the phone points seem ok, look on the bottom of your phones, and you should see a "REN number" this is the ring equivalence number, and is usually in the form REN 1 or REN 0.5 etc add up all the ren numbers of your phones and see what you get, if the REN comes to more than 4 you will have problems, if it is more than 5 some or all phones will not work. In short, the REN of your entire phone system must be less than 5. Incidentally, you MUST use a microfilter on every phone.
Hope this helps
