wireless network and quickbooks


not sure if this is the right place to post this but am sure if not arie will move to the right place. okay this is my problem.

have a business client currently on peer to peer networking. one machine is high end that is acting as the server for quickbooks enterprise 8 users. 7 of these users are rj45 connected 1 machine a laptop is wireless. laptop is a latitude d820, xp pro, 1g memory 128mb graphics. laptop is only 4 months old and has been working just fine wireless and using the quickbooks database. couple weeks ago some thing hit the building and basically all machine until they rebooted started acting weird. desktops when rebooted all was fine. laptop from that point on could not use quickbooks. error when opening was a permission violation a 80070057 invalid parameter per quickbooks techs. worked with q.b.'s literally for hours. per quickbooks this error is a known problem usually dealing with mcafee and just with laptops. as a final step i rebuilt machine from scratch. immediately q.b.'s error'd right away. after client raised some hell with q.b.'s cuz this package is very expensive they walked the laptop back to the closet and hard wired the connection low and behold q.b.'s worked. i have the wireless router linksys wrt54g setup with wep so i disabled security but still problem persist. every other function laptop uses for the wireless i.e. seeing others on the lan, printing to shared printer, every thing works fine. just q.b.'s not functioning with the wireless. q.b.'s says they have heard of this with wireless but they had no idea what the problem with wireless was. so i am asking the smart people on this site if you have an ideas what it could be.

as always your thoughts are appreciated cuz i've exhausted every trick i know to try.....greg

Well, the QB techs say it's a problem w/ wireless, but really it's a problem w/ QBs. There's nothing wrong w/ the wireless. It appears that QBs does not fully support wireless. They should say that. You could always just run a cat5 cable to the desk where laptop is used.

Have you installed the XP updated Wireless Client?
Do so and test.

It does slightly more than is advertised: http://support.microsoft.com/kb/917021

I am not optomistic. Did the QB people say why the error is thrown under wireless? I honestly do not believe it is a permissions issue:

i also do not believe its a permissions issue especially since it was working for 4 months then stopped. and the fact that every other function works just fine. my guess is qb is trying to push off this issue with making their program compatible with wireless. as big a company as they are and the fact that wireless is getting more and more into companies infrastructure they had better get on the stick.

hard wire is somewhat of a problem being that they do not have a drop down ceiling so would have to either follow the base boards of the wall or go out through the exterior of the building to where the user sits.

If the laptop user is in vicinity of a wired desktop, you can put a hub or switch between the gateway & the desktop (at the desktop location), and run a line from it to the desktop & the laptop.

What is baffling is that at one time it was working, correct? You say "something hit the building" . Pls explain that. Power surge? Network virus? Check the QB Enterprise logs for clues.

this i didnt know. so unplug the rj45 from the desktop plug that into a switch and then plug another rj45 back into the desktop and then one for the laptop. if this is what you mean then that can be done and only 15 feet from a desktop.

very baffling that for 4 months yes it was working then pow. client not really sure what happened but it does sound like some sort of surge they just told me that all of a sudden pretty much all desktops started to act sluggish. when they rebooted machines came back ok. each desktop has bitdefender with antivirus and firewall as well as spyware detection sft. machines are clean of bugs. i will have them check the log file and i will go to the forum and see if anyone else has this problem with laptops. qb techs tell me like i said before that the error code has been associated with laptops and with systems using mcafee. mcafee not a factor on these systems. i hate mcafee and norton.

thanks.

A friend of mine had a similar problem on a wired network.
quickbooks had worked fine for ages but then suddenly
started to give errors. It turned out to be a combination
of the speed of their hub (10mb) and the size of their QB
company file
Their qb company file was 120mb in size, once a 100mb hub was
put in in place of the old one it worked fine. I was told by someone
who deals with quickbooks a lot that this is a relatively small size for
a company file. Obviously the more invoices/customers etc added
increase the size of it.
He was using qB 2002

It might be worth creating a new test blank company file and see how that runs.

clients file is well over 200mb but there are on a 100mbps network. i also though the size might be to much for the 54mbps wireless to handle. plan on going 1g lan next year when they move into the new building and hopefully by then the n version of wireless will be ratified and function better. then the wireless speed will increase drastically.

Have you considered Powerline Networking?

200 mbs Powerline to Ethernet adapters are now available from Netgear and other vendors.

Forget what you think you know about Powerline. The stuff in the last three years built to new industry standards has been rock solid.

I read the article. This type of networking sure has come a long way. I remember years ago reading about an engineer (of some notability) who was working on a way to send tcp/ip & other protocols using the electromagnetic fiels surrounding large power lines. he got some good results but it seems the system was not financially viable. (takes away profit from existing network/backbone line owners)

I wonder how these new power line devices hold up to power surges & spikes, esp when using additional devices like routers & switches?

bill

read the article and im not sure if i want to go that way with this client. right now am leaning to hard wiring this laptop to a switch off one of the desktops just so he can use quickbooks.

doesnt make sense to me that qbs was working for 4 months on the laptop with wireless and now it wont but yet when hocked via rj45 works fine. i suppose the size of the database around 250mb might have just reached the max. for the wireless to handle but that is hard to believe also. might be slower in reaction time because of the size but why the permission violation dont make sense. qb hasnt been much help either in trying to figure this out other than to say its a known qb problem and their engineers have been working on it. not sure if that is true or not true but wireless is getting to be a big part of networking so in my opinion they should get a handle on this problem and fix it.

It would be cheaper to powerline than cable in most cases.

With a 200mbs link the laptop user can go anywhere in the building and connect. And connect faster than a cabled user.

Purchase powerline adapters from a dealer who allows a return. Use a brand name product such as D-Link. Test. Return the item if it does not sort the issue for you.

Because of the way they need to be built (around a transformer) it is more likely a power hit, surge or spike would take out your computers, routers and switches before harming a powerline device.

It is a fallacy that they cannot be used behind surge protectors, although I have never bothered.

That's what I thought. And that's why I wouldn't use them just yet, unless the ethernet cables were run through a UPS unit w/ AVR before connecting to any switches or routers or pcs. Unless the powerline adapter also has capability of 100% shielding the cat5 from ac current. I imagine a brownout or blackout followed by a power spike that blows out a router due to current traveling in via a cat5 cable from a wall outlet where powerline adapter is connected.

This cannot happen. There is isolation. You are much better protected in this sense than you are with a router connected to an ISDN, cable, or ADSL connection.

My point above was only that the device is more capable of surviving various power issues than most computer devices even if used without surge surpession. To suggest that it is vulnerable because of its connection to the Mains is misunderstanding the technology and its implementation.
