Depends on where you are testing to. Running a speed test from your modem location to say .... a server in New York, or L.A. is not indicitive of your service. You need to run a speed test from your modem location to the main engineering building with your cable company. THAT is the part your service provider is resposible for maintaining your rated speeds at. They control your "local area" speed, but when it leaves your town or city, ...it's on the net and subject to normal traffic.
As an example .... You live in Las Vegas and are paying for 8meg service for a cable modem. Cox LV can only ensure you are getting rated 8meg speed from your modem to thier main engineering building on MLK blvd. Now if you run a speed test from your modem to thier test server on MLK and find your only getting 4meg downloads ...then yes ...call your cable company, they have an issue to fix. If you run a test and find 8meg to the headend, then run another test to a server in New York and only get 4meg ...then it's the internet overall that is slowing your connection.
Keep in mind please too, that your computer comes into play as well. If you have a 5 year old PC that has never ran ScanDisk or a DeFrag, has 256meg memory, a 10gig hard drive, and is running WinXP... A trashed Hard Drive will slow you down too.
As for effects of Wireless Routers and gear. Check it to be sure it's 802.11g/n as they support throughput faster than most cable companies can provide in the first place. If you have an 802.11b router ... GET RID OF IT. Real life experiance says that a "B" router will only throughput 4meg/sec on average where-as a "G" will do about 30meg/sec and an "N" router about 80meg/sec. Apply that to our earlier example: 8-meg cable modem service thru a "B" router is useless as the router is the choke point to your PC.
Good Luck with it.
