But my horoscope told me to make harry Potter references !!!
Don't panic... just grab a towel, soak it in water, hang it on your front door, and then let me win on Saturday and you'll be fine.
On to some actual jury-rigging tips:
Fun fact about running on Wifi, if you think you are experiencing issues with signal strength and other wifi issues and you are literally unable to go wired, or relocate your router or PS3 to a more optimal location, a simple parabolic antenna made out of a metal mixing bowl (
or a tin foil lined mixing bowl, or whatever round-ish shaped object you have that you can then line with tin foil) positioned around the router and pointed in the direction of your PS3 (
or any wifi device really) can drastically improve your signal strength and availability. Your family may think you've gone crazy, but it will actually help (
No correcting my physics here, tzracer )
Also, since the whole "DMZ" thing has been mentioned before, another option (
one which I actually use personally) is many of the cable modems provided by your ISP are built-in modems/router combos, if you are then running a hard line from your modem to a separate router that you then use for wireless or your home network... you can connect your PS3 straight to your modem, bypassing your internal network and avoiding the extra layer of NAT'ing that would be setup by default in a scenario like that. (
Basically, if your modem has more than one LAN-out port, and you use another router off of the modem, you can run your PS3 straight to the modem and bypass your usual router.)
Finally: if you are really trying to pinch every bit of bandwidth out of your connection,
make sure you use as few coaxial splitters as possible between your modem and the telephone pole (
or whatever point is officially no longer on your property).
A normal 2-way coaxial splitter reduces signal strength by -3.5dB, and a 3-way is even worse (up to -7dB because it stacks) depending on how many TVs, or just cable jacks you have in your house alone (
nothing needs to be plugged into them or even running, the splitters reduce signal strength regardless), this can really start to add up. When I first moved into my place, I noticed that the cable provider set up a horrible configuration where as soon as the line got into my basement it connected to a 3-way splitter, and then from there would go on to split over and over again before actually reaching a wall-jack. (
I guess the previous owner reeeeally liked having options on where they could plug in their cable boxes and modems) Basically, if I had used another 2-way splitter just to connect my modem and a cable box into a single wall jack, my connection would've hit 4-5 splitters total before getting out to the world. Not even counting the extra noise from a 3-way splitter, I would be looking at -14 to -17.5dB right off my signal strength before I even tried to start tuning my internal network to figure out where my lag is... which is BAD... and borderline Impossible.
Don't quote me on this, but if I remember correctly, the
ideal signal strength for a cable modem is between -6dB and +3dB. Unless your ISP is crap or you're in a large apartment complex, or some other location where they may boost the signal strength, the signal strength initially running into your house should be right at
0dB (
which is considered the sweet spot). Outside the ideal signal strength range you will begin to experience dropped packets, wide variations in bandwidth speeds, and possibly even complete disconnects from your ISP. What I ended up doing was re-routing the cable jack in my office all the way back to that first splitter and plugging it straight into there (
on 3 way splitters, one of the jacks will still be a -3.5dB and two will be -7dB) and then letting the rest of my house run off the other lines.
If you log into your router, or modem interface, you can usually find your signal strength somewhere in the Connection information... hopefully it is as close to 0dB as possible (
might appear as dBmV). If you are running really low, and there's absolutely nothing you can do to clear the line then call your ISP. There are Coaxial signal amplifiers available, but last time I checked they do not work for modems... and will actually cause your modem to not connect at all (
this may have changed). Regardless, if you've verified that you have the cleanest route out possible but you're still having really low signal strength, calling your ISP and giving them the exact numbers should get them to your door.
Really, really, really, long story short, if you're not afraid of getting your hands dirty and tracing the coax cables around your house, you can pinch every last drop of juice from your connection by simply making sure your modem has the most direct route to the world as possible.
I dug around google for a minute and found this little graph showing an ideal configuration for an overloaded house (like mine)... it shows the use of signal amplifiers to the TVs, which I personally don't use, but most importantly note how the modem should be run all the way back to the very first splitter and plugged into the smallest dB loss jack.
EDIT: I just wanted to make note that I don't have 8 TVs in my house
but, like I said, splitters reduce strength regardless of whether or not anything is plugged in at the other end.
