does adsl modem & router use up more energy?

No not that much, may be  half to one dollar per month.

Make sure your computer is running at its most optimal speed. You need to make sure there are no extraneous processes running that start at startup. However, you will always be limited by the speed of your modem. You can always get DSL or Broadband.

If your modem supports usb and you have the drivers for it yes. You cannot use a modem hooked up to usb with a router however. My cable modem has plugs for both.

this has been an issue for along time with computer geeks however it has been found that both camps are right and that it is really up to personal preference computers do eat up more energy being  booted up but the fact that power surges and the mechanical parts in the drive in continuous use causes more where and tear including the , these two points alone show that they both kind of cancel each other out abit and any difference is so insignificant that it is more of a personal preference issue .

are you ona router? or directly from your modem? if router you need to be in 'PASSIVE MODE'

It varies way too much to say for certain. Depends on how hard  you're working your hard drive, cpu, how bright you have the screen, etc. Also wireless cards use up a LOT of power, turning it off when it's not needed will save you a lot

You still need a modem. The main difference is that you are using the cable line instead of the phone line. Cable lines are intended to work with images (TV) so they send and receive data a lot faster. I have a cable modem and it's 10 times faster than ADSL.

Im with Telewest. This is on cable rather than ADSL, i would always opt for cable as you can get huge bandwidths when no one else in your area is using the line and they garuntee your minimum bandwidth is what you pay for. It is generally more reliable for speed than ADSL i have found.

Routers are nothing more than special purpose computers. Like any computer it needs rebooting every now and then to clear the cache out. The cache size in residential routers run from 512Kb to 16Mb. Also different company and even models manage the Rcache more or less effectively. \nSometimes , with DHCP modem, the "lease expires" on the IP address your ISP assigns you. This means your WAN IP and the IP your route uses to identify your modem do not match. By unplugging the router and modem the router acquires the new IP address assigned by you ISP. The leases run 12 hrs, 24hrs, 7 days, and 28 days typically. That can very thought depending on your ISPs needs and wants.\n\nI hope this helps.

Usually that means that there is something up with the cable modem.\n\nThe first thing is to make sure you cycle the power on the modem every time you switch (between being connected directly to the router, computer 1 or 2). Every time the MAC address changes (for example if you change it from Cable Modem to Router TO Cable Modem to Computer 1) then you need to cycle the power. If you are just unplugging devices behind the router this usually isn't necessary.\n\nNow, any time you reboot the modem wait a minute and reboot the router.\n\nOtherwise, check the lights:\nPower: Should be steady. Blinking usually indicates a hardware failure or that standby is on.\nSend and/or Recieve Light(s): Should be blinking rapidly when plugged in to a device. Slowly or solidly can indicate a problem with your network cable or modem.\nCable: Should be solid. Blinking slowly or off indicates a problem with your cable connection (usually physically) or modem.\nPC/Activity: Should be blinking fast or solid. Blinking slowly or off indicates a problem with the modem, the cable between the two or the device plugged in.\nStandby (if applicable): Should be off. On or blinking indicates that it is in standby mode. Some modems remember this even when power is cycled.\n\nIf all the lights blink in sequence, stay on or stay off the modem is usually shot.\n\nHope this helps!\n\nEDIT: From the manual:\n\n"Light -Turns Off During Startup- If Turns Off During Normal Operation If\nReceive- The receive channel cannot be acquired - The receive channel is lost\nSend - The send channel cannot be acquired - The send channel is lost\nOnline - IP registration is unsuccessful  - The IP registration is lost\nPower - The cable modem is not properly plugged into\nthe power outlet\n -The cable modem is unplugged or is in standby\nmode. Press the Standby button"\n\nAlso:\n"f the solutions listed here do not solve your problem, contact your cable service provider. Before calling your service provider, try one of:\n• Unplugging and plugging in the cable modem power cord to restart the cable modem\n• Pressing the reset button on the rear panel\nRestarting or resetting the cable modem may take 5 to 30 minutes. Your service provider may ask for the status of the front-panel lights as\ndescribed in “Front-Panel Lights and Error Conditions” on page 44.\n\nProblem Possible Solutions\nGreen POWER light is off - Check that the power cord is properly plugged into the electrical outlet and the cable modem.\nCheck that the electrical outlet is working.\n-If the Standby light is on, the Internet connection is off. Press the Standby button to reconnect to the Internet."

best idea is to have the modem disconnected until the laptop is on the windows screen, since on a laptop the power saving is active all the time, and this can cause a problem with a device being detected. \nu can turn this off via the device manager.

That sounds like a DSL speed which should not be dependent on other users in your area unlike cable. The internet is busier on nights and weekends so just slower in general depending on which sites you visit.

You can turn a dsl modem off any time you want to. \n\nAnd its not required that you leave it on always. \n\nIf you are concerned about your online security. You can disconnect your LAN whenever your done, and reconnect when ever you want to.

Yes.\n\nIn addition to the post below, sometimes you may have to unplug the modem, disable network adapter, follow the instructions in the answer below, then turn off the computer for a while.

Precisely how much benefit you see will greatly depend on how far you are from the central office of the company providing the ADSL service. ADSL is a distance-sensitive technology: As the connection's length increases, the signal quality decreases and the connection speed goes down. The limit for ADSL service is 18,000 feet (5,460 meters), though for speed and quality of service reasons many ADSL providers place a lower limit on the distances for the service. At the extremes of the distance limits, ADSL customers may see speeds far below the promised maximums, while customers nearer the central office have faster connections and may see extremely high speeds in the future. ADSL technology can provide maximum downstream (Internet to customer) speeds of up to 8 megabits per second (Mbps) at a distance of about 6,000 feet (1,820 meters), and upstream speeds of up to 640 kilobits per second (Kbps). In practice, the best speeds widely offered today are 1.5 Mbps downstream, with upstream speeds varying between 64 and 640 Kbps. \n\nYou might wonder, if distance is a limitation for DSL, why it's not also a limitation for voice telephone calls. The answer lies in small amplifiers called loading coils that the telephone company uses to boost voice signals. Unfortunately, these loading coils are incompatible with ADSL signals, so a voice coil in the loop between your telephone and the telephone company's central office will disqualify you from receiving ADSL. Other factors that might disqualify you from receiving ADSL include: \n\nBridge taps - These are extensions, between you and the central office, that extend service to other customers. While you wouldn't notice these bridge taps in normal phone service, they may take the total length of the circuit beyond the distance limits of the service provider. \nFiber-optic cables - ADSL signals can't pass through the conversion from analog to digital and back to analog that occurs if a portion of your telephone circuit comes through fiber-optic cables. \nDistance - Even if you know where your central office is (don't be surprised if you don't -- the telephone companies don't advertise their locations), looking at a map is no indication of the distance a signal must travel between your house and the office.

Connection times out. Unless you have cable - I wouldn't leave it idle for longer than 2-3 hours. Shut it down, save the energy and further headache and frustration. :)
