Submission + - What causes degradation of wireless signals over time? 4

acer123 writes: Lately I have replaced several home wireless routers because the signal strength has been found to be degraded. These devices, when new (2+ years ago) would cover an entire house. Over the years, the strength seems to decrease to a point where it might only cover one or two rooms. Of the three that I have replaced for friends, I have not found a common brand, age, etc. It just seems that after time, the signal strength decreases. I know that routers are cheap and easy to replace but I'm curious what actually causes this. I would have assumed that the components would either work or not work; we would either have a full signal or have no signal. I am not an electrical engineer and I can't find the answer online so I'm reaching out to you.

Can someone explain how a transmitter can /slowly/ go bad?

  • Virtually all home wireless routers run way too hot. Feel the underside after it's been on for an hour. Hot. Open it up and put your fingers on the chips after its been running for an hour. Burn your fingers.

    My only thought is that it may not be signal strength but interference from other, nearby routers on the same channel.

  • I've had a similar experience. However, I have also moved into a new place.... and bought more furniture, drapes, wall hangings etc over the years. And more electronic devices such as wifi enabled tv, blueray, iPad, appletv, AirPlay devices. And I'm sure my neighbors have too.

    Is it (more) possible that your airspace is getting polluted? And the replacement models are simply better/more powerful?

    I know when I bought my iPad this year, my network went into vapor lock until I mov
  • Or voltage sag as you plug more things into your wall sockets?

    I've found that the Linksys BEFSR41 routers and WRT54G wireless routers work much better with little 12V fans installed, so you might experiment with greater external airflow to see if "blowing the heat out" is of any help.

What this country needs is a good five cent ANYTHING!
