Dear All,

I have already posted on another thread below but as that thread has
become very long I thought it may be helpful if I set out in detail
the problems that I am having.

Basically, I am having problems getting my wireless card to work.
This is complicated by the addition of a new wireless printer. I have
tried to give as much detail as possible in this post in the hope that
someone may be able to help.

Problem in a nutshell:

I am having the following problems:
- my PC will not connect to my router using the wireless card
(although it seems to work okay when connected through the Ethernet
cable);
- I am constantly getting the following error
messages:
1. Generic Host Process for Win 32 Services - Data Execution
Prevention Error";
2. svchost.exe - application error - "the instruction at "0x009a96bc"
referenced memory at "0x00000000". The memory could not be written"

Background:

I have had my PC for a couple of months and last week bought the
following:
- Netgear WAG311 wireless pci adaptor -
http://www.netgear.com/products/details/WAG311.php ;
- Netgear DG384 wireless router -
http://www.netgear.com/products/details/DG834.php ; and
- HP Photosmart 2710 all-in-one printer, scanner, copier which offers
wireless connection -
http://h10010.www1.hp.com/wwpc/uk/ [...] All-in-One

My first attempt at installing all of the above resulted in the error
messages referred to above. I did a few searches on the Web and found
several posts on different forums recounting problems people were
having connecting HP wireless printers to their PCs. People seemed to
be having exactly the same problem when trying to install their HP
printer wirelessly to a router. The problem appears to be one with
HP’s driver software (please see the section below entitled
“Posts in relation HP Printer problems”
).

I therefore concluded that the reason for these error messages must be
a problem with the printer software.

However, what I overlooked is the fact that the PC was not connecting
wirelessly to the router (I’ll talk more about this below).

I spoke briefly with HP Support in the UK and they said that they were
unaware of any problems and that I should try uninstalling the
software and then re-installing it and see if I get the same problem.
Based on the fact that people mentioned that they had been told to do
the same thing in their posts (without any success), I did not hold
out much hope of getting rid of the error messages.

So I uninstalled the wireless pci adaptor card (and removed it from
the pci slot), the wireless router and the printer so that I could
start again.

Last night the following happened:
- First, I re-connected my router to my PC using the Ethernet cable
(at this stage the PC did not have a wireless card in it and, as
mentioned above, I couldn't get the router and wireless card to
connect to each other when originally trying to do this anyway) – by
the way, I did not enable any WAP encryption;
- I then re-installed the printer's software and to my great surprise
it seemed to work – I had none of the error messages mentioned
before!
- However, I thought this was too good to be true and it was: when I
reinstalled the software for the wireless card and plugged it back in
the blasted "svchost.exe application errors" and "Data Execution
Prevention Error" messages returned!!

So although everything seemed to work fine when the router was
connected by Ethernet cable to the PC (i.e. the printer communicated
wirelessly with the router without any error messages), there seems to
be a problem when I install the wireless card (even though the
wireless card still doesn't actually connect to the router).

So I am now wondering to what extent the error messages are a
combination of the HP printer and the wireless card having
compatibility problems (whether with Windows Service Pack 2, each
other or something else) or whether it is just the wireless card that
is the guilty party.

I noticed a reference when installing the WAG311 software to Microsoft
hotfix Q815485. This only seems to be applicable to PCs without
Service Pack 2 and only when using WAP encryption. I have not
installed this hotfix (indeed when I tried to install it to see
whether it would have any effect, I was told that I couldn’t because I
already have Service Pack 2 installed).

I then did a search on google for “netgear” and “hotfix Q815485” and
found various comments which appeared to be saying that there are
compatibility problems between Service Pack 2 and Netgear wireless
cards.

Summary:

This all leaves me slightly confused because:

1. on the one hand: people appear to be having problems getting
Netgear wireless adaptors to work with Windows Service Pack 2
(although, I have not seen any references in relation to the netgear
problems to "svchost.exe application" and "Data Execution Prevention"
error messages (i.e. the error messages I have been getting)); and

2. on the other hand: I have seen plenty of reports of HP wireless
printers generating persistent error messages of the type I am getting
(again, please see the section below entitled “Posts in
relation HP Printer problems” ).

I toyed with the idea of uninstalling Windows Service Pack 2 but got a
message saying that lots of software may stop working if I do (it
seemed to mostly be a list of software that I have installed since
installing Service Pack 2).

My computer

- My PC (which I bought very recently is a Dell Dimension XPS -
http://www1.euro.dell.com/content/ [...] l=en&s=dhs

- I installed Windows Service Pack 2 soon after buying it
- Finally (and I don't know whether this should make any difference to
any of the above), at the moment I do not have ADSL broadband
connected - so the router is not connected to the Internet (I will get
connected at the end of next week).


I would be very very grateful if anyone could
help as I have no idea how to solve my problems.


Many thanks
