I don't think this is a major problem but it is definetly annoying. I have a Wireless DSL connection and about four out of ten times whenever the phone rings, I lose connection to the Internet. The first few times it happened, it didn't bother me because I think Wireless connection stills needs to be upgraded,etc. It only started to get annoying when I was researching for a school project when the phone rang and my mother answered, being on the phone for nearly 4 hours!!! (meaning I was without the Internet for four hours when I had a project due the next day.............yes I procrastinate). My question is if there is a way for this problem to be avoided or is that just the way it is? Thanks in advance.

A quick diagnostic checklist and practical fixes based on the thread so far (notes refer to , and ).

Most cases like this come from one of two problems: a phone/line interaction that causes the broadband link to lose sync, or radio-frequency interference between a cordless handset and the wireless network. The following tests will show which it is and point to the right fix.

Recommended tests (do them in the order listed):

  1. Observe the modem/router lights or system log when the phone rings. If the DSL/WAN light drops at the same time, the problem is on the phone line side.
  2. Plug a laptop directly into the router by Ethernet and repeat the test. If the wired link stays up while Wi‑Fi clients drop, it is radio interference.
  3. Note the phone type: plain analogue on the same copper pair, VoIP, or cordless (and whether the cordless base is near the router).
  4. Temporarily remove other telephone devices and rerun the test to see if a particular handset or extension triggers the loss.

Targeted remedies

  • Line-related loss: keep the modem on the master socket, isolate other phones from the modem’s signal (use a proper splitter or filters at telephone devices), and test with other phones disconnected. If the modem still loses sync, ask the ISP to run a line test.
  • Wireless interference: move the cordless base away from the router, change the Wi‑Fi channel (use 1, 6 or 11 on 2.4 GHz), reduce channel width to 20 MHz, or move to 5 GHz if the router and clients support it. Replacing an old 2.4 GHz handset with a 1.9 GHz DECT model often removes the conflict.
  • General: update router firmware and check modem/router logs for recurring timestamps; persistent problems merit an ISP line quality check.

This sequence separates the two root causes quickly and points to low-cost fixes before escalating to replacements or ISP support.

it is porbably because your phone has the same transfer speed as the wireless transmitter.

Any way I can change that without damaging anything? Thanks for your reply.

Do you have a wireless ADSL modem ? AKA does the modem plug into the phone line, because if thats the case you need a ADSL line filter that you plug onto the socket that the phone plugs into (there about $20 au dicksmith, harveynormal etc.. have em).

The reason for this is the phone w/o the filter will throw noise onto the bandwith that the modem is using 4khz up (I think) and therefor force the basted to D/C
