It's rare to change proxy settings for a small or home network. Proxies tend to be something used in school or business networks, and when there are servers that secure or that cache network traffic for the organization.
While they do have IP addresses, network proxies aren't particularly related to IP addressing itself. They're an intermediate hop and effectively a special-purpose IP router that's intentionally placed into the network path to the intended destination for your network connections of the particular protocol(s) involved.
On more recent releases than your 10.5.8, managing the proxies for the various protocols is a set of checkboxes, and unchecking those will clear all proxies. Uncheck all of those, unless you're on a network that requires proxies.
As for your question, please post a link to the proxy settings article you were reading, and please indicate what attributes of your network that you are resetting that "works on and off". If you've tweaked various settings, you'll have to find and untweak those settings, or (less desirably) delete the whole interface and re-add it.

Ok sorry my explanation wasn't very good -
I can't find the article but what they told me to do was to go to network settings and then to proxies - I then selected web proxy and changed the the number entered in the "bypass proxy settings for these hosts and domains"
This then caused my interenet to work fine for a couple days before stopping.
SO then I went to TCP/IP settings and I kept switching between "using DCHP" - renewing DCHP lease - and using DCHP lease with manual address and changing these numbers.
About a week ago I checked the IP of my other mac and entered the same but with a different last number and it was working fine until now - sometimes it works sometimes it doesn't.
I don't know what else to do and I can't find the article I was reading so I don't know specifics -
Is there a way to just reset an IP or give myself a new working one??
Also if I was to delete whole interface and reset it how would I do that - and would it guarantee to work??

Please describe your network in a little more detail — you have two Mac systems. What sort of local network are these connected to; WiFi or wired network? Is this a home or school or business network?
I'll make some assumptions with the following...
Are you on a private (home) network, or are you on a school or business network?
If you are on a private (home) network...
- Please shut off any of the web proxy settings that may have been enabled here. Those settings are unrelated to the configuration typical private (home) networks.
- Use DHCP-assigned settings only. Don't self-assign IP addresses.
If you're on a school or business network, please contact the organization's IT folks for assistance with setting up your Mac systems.
Are you on a WiFi network? (I'm guessing you are, based on your descriptions.)
If you are in an apartment building, or have neighbors or businesses located within a hundred meters or so, or are in some other sort of densely-populated area, and if you are using WiFi to connect to the Internet, then it is possible that you're experiencing the effects of WiFi interference. Too many WiFi routers in too small a space can cause problems similar to what you are describing. If so and if your ISP-provided gateway has the option (and many do), connect directly to the gateway device via an Ethernet cable from your Mac, as a test. See if that works more reliably.
Use DHCP. Save for specific networking configurations, please do not self-assign IP addresses when DHCP is available. Please don't pick random IP addresses. Even once you're familiar with the local network layout and with how IP routing works, it's still usually easier and better to use the DHCP-assigned addresses and DHCP-assigned DNS services and DHCP-assigned gateway router addresses.

I would just delete
and start all over again.
If you do not want to delete that file, then remove all your Proxy entries. Uncheck all Proxy checkboxes. And set your Network Preferences -> Advanced -> TCP/IP tab -> Configure IPv4: Using DHCP. If you want, give your TCP/IP tab -> DHCP Client ID: a simple value (to identify your Mac from other Macs on the network).
