Problem! Ethernet connection keeps cutting out.

[Domestic_Ginger]

My ethernet connection keeps cutting out. If I disable the device and re-enable it it works so I think my router is fine. It usually happens in wot using TS.

tried reinstalling the drivers; have not found old drivers to try. Anyone have any ideas?

Probably a compatibility problem between your NIC and switch.
I have the same problem with an old IBM T40 and Draytek 2820.
Similar goes for a pair of brand new Dell Optiplex 790's and an old Genius 10/100 switch I have. The connection keeps flapping. Fixed it by connecting them to a gigabit switch instead after much unsuccessful driver and settings faffing.

Try different NIC drivers.

Try forcing the speed and duplex.

Check your MTU size on the router config.

Okay, have ordered:-

1) as the quickest fix I have tried the drivers directly from realtek, this was a bit late last night but I can not remember having any problems so will see if I get any probs. failing that.....

2)Will try the Duplex speed forcing but I am a noob. Will wiki MTU later! Recommendation for guide/software? EDIT: Device manager -> Network adapters -> your NIC, right click and select properties -> advanced -> speed & duplex.


3) will dig out the netgear and replace current router (this seems the most labour intensive).

It looks like the 7.048 drivers were rubbish and the 7.05 from the realtek site seem to have fixed it. I did not have one cut off last night.

I'll have a look at the speeds sometime as my internet is a bit slow but my comp does seem a little bloated.

Thanks for the help peeps.

This is a weekend problem. Sundays especially. I have adjusted my settings and forced 100mbit/s (?) and full duplex and have not had another hiccup. I have forgotten my router password so am unable to find out if it is on negotiation or a set value and cba to reset the thing.

This could be a problem if they are both on different settings, apparently I could lose data?

Will elevate to defcon3 if I get more problems.

That's a funny thing. I had the same problem start yesterday. I reset my TCP stack. Still cuts every hour or so. But it's been fine today O.o

Anyone able to offer a reason?

EDIT: crap cakes! It went as I was writing this post. Talk about luck.

[Domestic_Ginger]

Set to half duplex......

Will think about changing router.

Ferret, you have a Realtek® 8111E , 1 x Gigabit LAN Controller(s).

I have a Realtek 8111C/D(L) chip (10/100/1000 Mbit).

Not sure if there is a coincidence. but they both use the same drivers.

[shaithis]

The 8111E chip (at least on it's own) isn't the problem.

I have multiple machines running that chip both as on-board and using some TP-Link PCI-E cards....all working flawlessly - including on some ESX installs where they have been hammered 24/7 for months.

As far as I know I have an Intel controller on my motherboard.

Update.

Router change has not fixed it. Have swopped microfilter and am awaiting next disconnection. DIdn't disconnect once last night!

[iamlorro]

glad that all seems to be okay now.

I was going to ask if you have anything else on the network that you have the same problem with?

[ferret141]

An update of my problem. Investigated further. Not a problem with ethernet. Talked to ISP. Investigated further. Incorrect configuration at exchange was causing regular packet drops (i.e. every 8 mins). Fixed now.

But now I'm suffering from a HR faulton my line.

[Domestic_Ginger]

Okay, my problem started again.

Phoned Plusnet and the man thought it was my router. Both a zyxel and a DG834 v3 where not ADSL2+ as advertised. they changed my line in december without telling me. He sent me a new router and all is fine now. Should have phoned them earlier tbh.
