Gearbox101 Level 1 Level 1 (0 points)
I have WIFI enabled on my Iphone and I connect to my AT&T DSL Wireless connection via my Linksys Router. If I disconnect and then re connect my signal is full strength then over time the signal weakens to only on dot why is this occurring ?

IPhone, iPhone OS 3.0.1, Dell Inspirion 1000

    When the connection is made, the phone initially shows all WiFi bars regardless of signal strength, but within a minute or so, the actual signal strength is shown.

    Thanks. My computers report a strong signal here in the room with the router the computers in oter rooms report good connections the Iphone is less than 2 feet away from the router but often reports a weak signal now at work I am about 12 feet away from the router (Linksys like the one I have at Home) and it always reports a strong signal. Should I suspect the router at home going bad ?

    When there multiple connections, the router may use different channels and outputs. Try rebooting your router.

    I noticed I actualy have a stronger signal when I take my phone into the next room than when I have it in my main office room , and blue tooth only works with headsets I have tried to use my computers bluetooth to discover my iphone and none of them discover it.

    I have tried to use my computers bluetooth to discover my iphone and none of them discover it.

    The iPhone doesn't support this type of BT connection.

    Did not know that thought it did my old Pantech Dou C810 would let me BEAM items over to the computer and vice a versa. The balckberry will too I think, so the Iphone dont support bluetooth excahnge between computers or other phones to include Iphones ??

    No. you can't do BT file transfers to computers or other phones with an iPhone.

    Maybe we should push Apple to have an Harware or software update to allow it ?

    Thanks

    You can suggest this on the iPhone Feedback page:

    http://www.apple.com/feedback/iphone.html

    This has been requested by others. I suspect there are DRM issues involved with iTunes music/media factoring in.

    I have an AEBS (the older 2007 version NON dual band). My iphone signal strength varies from 2 to 3 in the same room. I have two computers in the house and their signal bars always stay full. I have my AEBS set to n (b/g compatible). One day, I'll get the newer dual band AEBS. But why on Earth would the iphone report only two bars in the same room??
  • modular747 Level 6 Level 6 (17,035 points)
    "Bars" are not an absolute measure of signal strength and don't correlate between different devices. Unless you get a reading of dBm, they are only relative to that device's meter. 3 "bars"on the iPhone could be equivalent to "full bars" on your computers. Also, some iPhone cases and even the way you hold the phone relative to the antenna location will affect received signal strength.

    If you have 3 devices connected to your router at the same time, the signal is divided across 3 channels with a fraction of the routers rated RF output send to each channel. Older routers can have frequency drift, resulting in reduced received signal strength. Sometimes rebooting the router will improve the signal. Getting a newer, dual band unit will help.

    I have a clear back case on my iphone now (plastic). The iphone is the one where the bars seem to fluxuate between two and three (full meter) bars....even in the room with the AEBS. Since I have my AEBS set to n(b/g compat), it should work for everthing in my house. I never see bars drop on my computers.
  • modular747 Level 6 Level 6 (17,035 points)
    Again, "bars" have little meaning when comparing different devices. How many bars do you get when connecting your iPhone with another WiFi source?

    Do you actually have problems maintaining a WiFi connection with your iPhone or are you just bar obsessing?
  • powerbook1701 Level 3 Level 3 (555 points)
    ouch. Just kidding. Well, my two computers (one next to the AEBS and the other several rooms away), always have full bars. My iphone flux's between 2 and 3 bars (3 being full) while in the same room as my AEBS. I am more trying to see if it's a wifi issue with the phone (meaning it's ability to receive wifi) or my AEBS. Since I never see any bars drop on either computer, I am just trying to figure out IF there is an issue. I guess I am obsessing about that (since you pay a lot of $ for the iphone, I want it to operate like it should).
