What skorpio1 says is correct; a cheap splitter is of no use. Try lamington Rd, if possible try to get a branded splitter. Regarding the low speeds thru the wireless
& getting the hissing sounds in your phone.
1) the tel wire coming to your house should first terminate at your splitter/
router/modem and ONLY THEN go to other tel instruments. Since you don’t have a splitter I presume that your wire has joints entwined together, which can cause
noise/low speeds due to oxidation/dirt between the wires.
2) If the tel instrument used is a cordless, then at what frequency does it operate on. If its 900 Mhz then it should not be a big problem & the above point holds. If it’s a hi power one it may be operating on 2.4 Ghz same as most wireless routers, in that case you will have to change the channel its operating on. In case you do this remember to select the same channel on the
laptop to. In any case a splitter is a must.
3) Another cause of less speed could be loss of signal strength which can be caused by the distance between the WiFi router & your computer plus other obstructions like walls, partitions etc
4) Another reason for low speeds could be amt of RAM, the number of TSR’s operating in the background (they consume memory), OS updates going on in the background, the amount of security used on the laptop like firewall, vaccines, sniffers for BOT’s etc though it should not reduce the speeds like in your case.
5) There could be a remote possibility of someone else riding piggy back on your network & hogging the bandwidth, so If possible use the WPA2 PSK if possible also shut of the SSID transmissions of your wireless router, but before doing that select the option on your laptop which ensures that you can log in even if the SSID is not transmitted. I have done that on my laptop, I use Vista Home Basic. If you want check out the security aspects at
