I have a weird problem on my Win7 machine that I couldnt find any solutions for.

I have a router with built-in modem and a built-in wireless.

My problem is as follows: When my PC is directly connected to my router through a cable I get many connection problems, among these:

  • Windows update never works and gives error 8024402F, according to microsoft site this is WU_E_PT_ECP_SUCCEEDED_WITH_ERRORS

  • Certain websites dont work correctly, for example when accessing the new I often get a connection error. After refreshing a few times and eventually get in, clicking on any email message never displays it.

  • When I search using or sometimes I get 1-2 entries of results and my browser seems to be still fetching data but nothing is fetched, I have to refresh again to get the whole page to complete.

  • Many sites simply give me connection errors where I have to refresh multiple times for them to show up.

  • Some https sites don't work.

When I use wireless connection to my router, all of the above problems disappear and everything works fine.

When connected through cable, if I go to Network and Sharing Center then under View your basic network information and set up connections I click on See full map I get the following diagram:

MyPC ---> Hub ---> BRCOM Router ---> Internet

When connected through wireless, the diagram is as follows:

MyPC ---> My Access Point Name ---> Internet

My question is as follows:

Could this be a problem with the cable I am using? I currently don't have another cable so I cannot test another one unless someone tells me that this could be a possible cause. (Edit: I used another cable and tried all 4 slots in the router. Did not fix)

Could this be a problem with the network driver? I have used the dell website for my PC to fetsh the latest driver for my network card.

Could this be a different problem in routing?

Any ideas?


I don't know why there is a 'Hub'. Physically, my PC is directly connected to my router which has a built-in modem and is also my wireless AP. My router is directly connected to my phone line. So physical diagram is:

My PC ---> Router(includes Buit-in modem, includes wireless) ---> phone line

This question came from our site for system and network administrators.

you show the AP and router both connected to the Internet. This is unlikely. Can you do one diagram that includes both devices? – Paul Ackerman Aug 2 '12 at 13:30
I think this is a faulty cable, replace it, don't think too much in to it. – Alex Berry Aug 2 '12 at 13:30
Broadcom doesn't make routers... they make chips FOR routers... so what kind of router is this really? – TheCompWiz Aug 2 '12 at 13:41
@TheCompWiz Clearly, it's whatever cable modem his ISP provided for his home broadband connection. Needs to be moved to SuperUser. – HopelessN00b Aug 2 '12 at 13:54
@Paul Ackerman see my edit above – Alaa Masoud Aug 2 '12 at 14:13
