When the Fault Is Upstream: an Optus 250M Plan That Was Never Activated, and a TPG PPPoE Line That Connected but Had No Internet

问题其实在运营商那一侧：Optus 250兆套餐根本没激活，TPG 拨号已连上却上不了网

Two recent Sydney jobs where the router was fine, the cabling was fine, and the fault sat one step upstream with the provider. One student was paying attention to the wrong thing entirely: their Optus 250Mbps HFC plan had never been activated, and the router had quietly been running on its built-in SIM backup at about 30 Mbps. The other had a TPG PPPoE line that dialled in successfully and held a provider-assigned IP, yet still could not load a page.

最近两个悉尼的单子，路由器没问题、布线也没问题，故障出在上游的运营商那一侧。一位同学一直找错了方向：他的 Optus 250 兆 HFC 宽带根本没有被激活，路由器一直悄悄跑在内置的 SIM 备份上，约 30 兆。另一位的 TPG PPPoE 拨号明明成功、也拿到了运营商下发的 IP，却依然打不开网页。

The router looked perfectly online, so nobody suspected the plan. But the traffic was not coming from the HFC line at all — it was riding on the routers built-in SIM backup at around 30 Mbps. Optus support confirmed the broadband order placed back in March had never been activated, which is also why no broadband charges had appeared.路由器看上去联网完全正常，所以没人怀疑到套餐头上。但流量根本不是走 HFC 线路的——它跑在路由器内置的 SIM 备份上，速度约 30 兆。Optus 客服核查后确认：3月份下的宽带开通单一直没有被激活，这也解释了为什么一直没产生宽带费用。

Case one: the plan looked live, but it was never activated

案例一：看着已开通，其实从没被激活

This student had gone into an Optus store in March to sign up for a 250Mbps HFC plan. The NBN box and the router arrived, they set it up themselves, and it connected — but the speed was terrible. They came to us assuming the cabling or the router configuration was wrong.

We asked for the activation emails and the account details before touching any hardware.
Optus support checked the account and confirmed the March order had never been activated. No broadband charges had been raised in that whole period, which lines up.
The reason the router still worked: it has a built-in SIM, and the mobile data backup was carrying everything, at roughly 30 Mbps — a long way from the 250 they had paid for.
The fix was not technical at all. They went back to Optus by phone and in store to re-place the activation, after which the router picks up the fixed line on its own.

这位同学 3 月份去 Optus 营业厅办了 250 兆的 HFC 宽带，运营商把 NBN 盒子和路由器都寄到了，他自己配置好也能上网，只是网速很差。找过来时以为是线没插对或者路由器配置有问题。

我们没有先动硬件，而是先让他提供宽带开通邮件和账号信息。
经 Optus 客服核查，3 月份那笔开通申请因为某种未知原因一直没有被激活；这期间也确实没有产生过宽带费用，两边对得上。
路由器之所以还能上网：它内置了电话卡 SIM，实际是移动数据热点在跑，速度三十兆左右——和他买的 250 兆差得很远。
解决办法完全不是技术层面的：让他重新联系 Optus 电话客服或线下门店重新申请开通，之后路由器自己就会接上固定宽带。

Case two: PPPoE connected, IP assigned, still no internet

案例二：PPPoE 拨号成功、也拿到了 IP，就是上不了网

A different student, on TPG with a TP-Link router and PPPoE dial-up. Their connection dropped, they called support, re-entered the PPPoE settings as instructed, and the router admin page then showed the connection as established with an IP handed down by the provider. And yet nothing loaded.

When the router says connected and holds a real WAN IP, the local side has done its job — the credentials, the cabling and the dial-up itself are all working.
That pattern points upstream: something on the provider side had not been refreshed after the outage.
They contacted TPG again, support ran a remote refresh on the service, and after one more device reset and re-dial the connection came back to normal.

另一位同学，运营商是 TPG，TP-Link 路由器，PPPoE 拨号上网。网络突然中断后他联系了客服，按指引重新配置了 PPPoE，路由器后台显示网络已连接、也拿到了运营商下发的 IP，但就是不能上网。

路由器显示已连接、并且拿到了真实的 WAN IP，说明本地这一侧的活已经干完了——账号密码、线路、拨号本身都是正常的。
这种现象基本指向上游：断网之后运营商侧有些东西没有刷新过来。
他重新联系了 TPG 客服，客服做了远程更新操作，之后再重置一次设备、重新拨号，网络恢复正常。

Why this is worth knowing

为什么值得记住这一点

Both of these looked like home-network problems and neither of them was. When you are configuring things yourself it is very easy to fall into self-doubt — is it me, or is it them? A few checks settle it quickly:

If the router reports a healthy connection but the speed is nowhere near your plan, verify the service is actually active before you buy new gear.
If the router dials in successfully and holds a provider-assigned IP but nothing loads, the local side is fine and the provider needs to act.
Keep your activation emails and account number handy. Half of these calls are won by having the right reference number in front of you.

这两个案例看起来都像家里网络的问题，但都不是。自己在家配置的时候很容易产生自我怀疑——到底是我的问题还是运营商的问题？其实几个动作就能判断：

如果路由器显示联网正常、但速度和套餐差着一个量级，先确认服务是不是真的已经激活，再考虑买新设备。
如果路由器拨号成功、也拿到了运营商下发的 IP，却打不开网页，那本地这侧没问题，需要运营商动手。
把开通邮件和账号信息留好。打客服电话时，手上有正确的单号，一半的事情就成了。

Result最终结果

Neither fault was in the home. Optus had never activated a broadband order from March, so the router had quietly been running on its built-in SIM backup at about 30 Mbps instead of the 250Mbps plan; re-placing the activation resolves it. On TPG, a successful PPPoE dial with a provider IP but no traffic was cleared by a remote refresh on the provider side plus one device reset and re-dial.

两个故障都不在家里。Optus 那边 3 月份的宽带开通单一直没被激活，路由器其实一直在用内置 SIM 备份跑，约 30 兆，而不是 250 兆套餐；重新申请开通即可解决。TPG 那边 PPPoE 拨号成功、拿到运营商 IP 却没有流量，由运营商远程刷新后，再重置设备重新拨号即恢复正常。
