    I just bought a VTech 2.4G cordless phone. Since than my laptop (with WiFi 802.11b) can not connect to my wireless router close to the cordless phone base. Is this a coomon problem? Is there anyway to fix, or I have to return this one and get a 900Mhz instead?

    I had the same problem too. I ended up getting a 900Mhz phone. -John

    Just change the channel w/ your phone or w/ the wireless adapter settings in your laptop. I have four 2.4ghz phones (vtech & AT&T) in the house & my wireless is not affected in any way.

    I have a Netgear MR814 Wireless (802.11b) Router which works great. I am thinking about getting a 2.4 Ghz cordless phone, but the sales people at both CC and BB told me the the phone will interfere with wireless network. Is this true or can I just change channels on router if there is a problem?

    Or should I stick with a 900 Mhz or 5.8 Ghz cordless?

    It's obviously easier to just buy a different frequency phone if you're making a purchase decision. I have two 2.4ghz phones, and I just changed the channel on the wireless router to fix any interference.

    There is no solid answer to this question. I have the same router and 2 2.4GHZ phones w/ no problems. If you experience any difficulties as others have said change the channel on your phone.

    Changing the channel makes it working as oppose to not working before.

    However the bandwidth that you get is probably reduced.

    2.4GHz phone do not do any thing better than 900MHz (unless you are listening to HIFI music through the phone.

    Both technologies work fine, but my 2.4 GHz Panasonic w/digital spread is vastly superior to my old Sony 900 MHz w/digital spread in terms of both range and call clarity (on the Panasonic, it's barely distinguishable from a hard-wired phone). So in that case, I would have to disagree.

    Getting back to the original topic, phone interference with wireless routers is simple to address. Just change the channel on either the phone or the router and you should be fine.

    The 2.4 GHz phones also are superior in range than the 900.

    Most of those people are clueless (no offense to the BB people here on the forums) but my BB people told me a 2.4GHz phone wouldn't interfer with my MR814. Which it did, only after I found out later. :(

    I don't know guys.
    I have a 2.4 Video system going, 2.4 Phone and 2.4 D-link Wireless. All playing along fine.

So in that case, I would have to disagree.? Yeah using 900MHz, I notice that when ever someone calls me I do not understand what there are saying, may be I should switch. j/k ;) ;) ;).

    2.4GHz phones is one of the many ?senseless? products that are brought to the market so the people will keep buying. Together with marketing it works very well to drain our pocket, and interfere with our Wireless.

    ========================================

    If you would have the instrument that analyzes the transmitting signal you would find that there is interference.

    The question is how much?

    Every transmitted signal has a bandwidth. E.g. the transmission is not 2.4GHz, but a band bellows the central point and above the central point the further you move from the center the less is the signal, switching channel makes it functional by reducing the interfering signal.

    However since the channels are very close it is still there ?interfering?, and probably reduces the quality of the Wireless Network.
