557002 2007-06-07 09:25:00 Of the seven weather stations that DSE list, 4 use 433.92 (or "433" or "434") MHz, two use "868" (probably 433.92 X 2) MHz, and one doesn't say. But I doubt if the receivers are very selective. ;) So they could easily be confused by other transmitters nearby.

Perhaps the satellite dish has been blown out of line? Cable corrosion?

WiFi is great, but I like wires. :D

If trying different channels does not fix it, it may just be a weak signal.
A wireless booster may be what you need.

Are you sure it is not the satellite signal that is dropping out.
You could try connecting the laptop by ethernet just to make sure there is no problem in this area.

557004 2007-06-07 09:45:00 According to the supplier, who installed the entire system, this device is commercial grade and the exact same device used in large hotel installations with no trouble end quote!

Im going to say sorry before I says this, I am woman, I am understanding what you are all explaning, but I need to clear up some areas that are problems for me :o

When it is connected nice and smooth it shows 54 . All of a sudden, with nothing in the house moving or changing, no phone ringing, the signal goes . Sometimes when I hang over it it will say 12, sometimes 2 . Now it is 2 but 2 minutes ago it was 36 - 48 . Is that fluctuation normal?

At the moment the portable is about 25 metres away from me . Is it sending this *errr* DISTURBANCE out when it is just sitting there, perhaps checking in with the base, which is about 4m away from me .

Am I better to get rid of the portables and get a wind up phone?

and now its up to 54 and HE is at 36 . :p

557005 2007-06-07 09:51:00 I have to connect up through the ethernet tomorrow to change the channels.
Err .. I need to go through the tcp/ip properties and manually put in ip address etc. With your ip address setting in your laptop changed to those below, try accessing it while unplugged from the satellite – ie. unplug the wireless unit from the satellite.

Errr .. I do need to be connected via the ethernet cable to do that yes?

557006 2007-06-07 11:11:00 have you tried changing the channel on the wifi? plod (107)
557007 2007-06-07 11:25:00 Thats happening in the morning Plod. I will do that before trying anything else.

Can you answer my question in #14 about that. It might sound stupid, but I have to access the device via the isp number .. (god I hope im explaining it right) to change it from channel 1 to 6. I have to be online via the ethernet cable to do that ? YES ??

557008 2007-06-07 13:26:00 I have a 2.4Ghz cordless phone right on top of my Linksys router and I have no issues whatsoever. We also have 2 more subordinate phones all running at the same frequency and again no issues. Laptop/IPAQ all connect well at 54MB (I know I;m never going to get it:D).

The biggest source of the interference would probably be the chicken wire in the roof. Just imagine, anytime any signal from any device is emitted/broadcast, the roof interferes and maybe even atmospherics in rural areas. One by one, turn all the devices off and then on and see if you can spot the culprit. Keep the microwave closed:D

557009 2007-06-07 18:59:00 As it is, in my very congested area where I live, I get all sorts of RF and other "splatter" interference .

The area in which I live is very freq-infested and there are really some serious fights for allocations . . especially with every kid in grammar school up to college and beyond having their own cell . . we even have cells with GPS in them on dog collars .

The neighborhood is close-fitted and the need for hardwiring is an absolute . If I use my wireless phone (2 . 4Ghz), I am forever searching for vacant channels .

My television (aerial mode) gets "hit" all the time from various sources and I cannot get certain channels at most times of the day .

I have out of necessity gone as far as I can in hardwired systems . . the phones and tvs are the exceptions .

Not really suffering for speed . . . as wired things appear to have an edge over wifi or over-the-air systems needing to encode-modulate-transmit-receive-demodulate-decode, I am actually better off this way .

One thing I did was to buy wireless phones (43-50Mhz and 900Mhz) . . in lower frequency range and so far have not had a hit in over two years .

Backwards progress is sometimes a better deal with everybody buying the latest and newest systems I get a lot of open freqs and areas for communication that are now considered passé .

Some systems here in the US are running 5 . 8Ghz as the 2 . 4Ghz band got too crowded . We don't see the newer Euro 1 . 9Ghz stuff here yet .

The FRS/GMRS freqs are from 462 . 4550 to 467 . 725 and appear to not be a concern on paper . . but there must be some sort of multiplier problem as the radios I use also tore up my wireless phones on the higher freqs . . . so I went to the lower ones .

I DO know this however:

Take care when thinking of 5 . 8GHz phones and easily discounting them as a problem-maker .

In reality only high-end 5 . 8GHz hardware transmits both ways on that frequency . Most so-called 5 . 8GHz cordless phones transmit from base to phone on the 5 . 8GHz . . . . . . and transmit from phone to base on 2 . 4GHz or 900MHz to conserve battery life in the handset .

Most manufacturers claim a range of about 30 m (100 ft) for their 2 . 4GHz and 5 . 8GHz systems, but cheaper units often fall short in actual range .

Most times . . . . the higher frequency brings an advantages .

The 900MHz and 2 . 4GHz band are increasingly being used for a host of other devices including:



baby monitors
microwave ovens
Bluetooth
wireless LAN
. . . and thus, it is likely that the cordless phone will suffer interference from signals broadcast by those devices .

It is a common misconception that it interferes with the 802 . 11a wireless standard, as the 802 . 11a standard operates usually in the 5 . 180GHz to 5 . 320 GHz band . . . . . . . whereas this is 5 . 8GHz .

However, 802 . 11a devices can operate in the 5 . 8GHz range if configured to do so .

Wireless phone handsets as they exist, are designed for connection with a local wired service(LWS) . . . . not using traditional mobile phone networks . . . . most commonly using digital technologies: namely, DECT, 2 . 4GHz unlicensed spectrum . . . . or 802 . 11a/b/g standards-based wireless LAN technology .



For all youse Euro-guys and gals:

The recently allocated 1 . 9 GHz band is reserved for use by phones that use the DECT standard, which should avoid interference issues that are increasingly being seen in the unlicensed 900 MHz, 2 . 4GHz, and 5 . 8GHz bands .

557010 2007-06-08 01:25:00 Well I have been trying this morning to get the laptop to access the ip addy (probably wrong name) :P But i cannot access it, I have to make the assumption that do to that I have to be connected to the net via the ethernet cable.

There is this morning no change, connection has been intermittent, though not as bad as in the past. The portable is disconnected totally, even has the batteries out of it. And still it disconnects in the bedroom.

Oddly enough, we have a radio in the bedroom. For some years we have had no trouble with getting the one or two stations available to us, though in the last bout 5 months, we cannot even run a radio in there.

:illogical

I have to do this to access the wifi device to change the channel
