From: John John - MVP on 29 Oct 2009 15:10 Well, as an aside subject, for security reasons I wouldn't connect to the internet without going through a NAT router, passing through NAT is probably one of the biggest security measures that you can take when connecting to the internet.

Routers usually have a feature which allows you to > "copy" this MAC address onto the WAN port. Was true when ISPs attempted to enforce the use of a single computer connected to their service. As routers became more prevalent, they lost that control since it is trivial for routers or operating system to define any WAN-side MAC address they want. Now they just lock in on the MAC address for the cable modem when you provision your modem to validate your use of their service. The OP should not be attempting to change the MAC address of their cable modem.

That means adding the sigdash line ("-- ") to delimit the start of your signature. - Keep signatures to 4 lines, or less (preferrably less). The disclaimer portion is utterly superfluous. No one here can establish a legal agreement to establish a service contract level for support. Presumably even your "JetBrains Omea Reader" NNTP client has a means of inserting signatures, so it should be delimiting them by using the sigdash line. However, should you decide to continue inserting a properly delimited signature in your posts, remember that signatures ALWAYS go at the bottom of your posts whether you top- or bottom-post. There is only the start-of-signature delimiter. There is no end-of- signature delimiter. So when configuring your newsreader to add a signature, also configure it to append it to the END of your post (some newsreaders are deficient in this regard, notably Outlook Express although a registry edit exists to position the signature at the end yet many users don't use it, including many OE-using MVPs).

For the moment I am testing another computer and every time I > switch between the two computers I have to call the provider Just a thought, since you didn't make it clear: Is the adapter in the original machine integrated into the MB or is it a plug-in card? If it's the latter of course, you could simply switch it between machines for the duration of your testing. (Bit of a chore but not *too* bad and better that calling the isp each time). |
