Another killer e2200 nic problem thread

[dovah-chan]

I haven't posted on this site in over a year so I'll make this quick as I have been busy lately but this has been a major pain in the behind yet not quite to the point of breaking the camel's back.

You see on my MSI G45 motherboard, it has the unfortunate curse of having a killer nic at first. But whenever I bought the motherboard I wasn't using a LAN connection at all so I didn't care what nic the board had. Now after a few months of having a powerline adapter my connection times out and rejoins continuously on things such as IRC and steam chat. But that is the least of my problems at the moment.

The main problem is my download speed over LAN. It's cut in half of what it is when I download through my phone on the 5GHz band. But when I insert my cheap wireless adapter then speeds are normal. Here are the examples:

Downloading through LAN on PC

Downloading through Wi-Fi on PC

Downloading through Wi-Fi on phone

Now that the problem is made aware of here are the steps I have taken to address it:

-Tried different routers (have tried a netgear R6300v2 and a netgear WNDR3700v3 w/ DD-WRT installed on it) only to achieve the same results

-Tried switching between half duplex and full duplex (both with the same results)

-Turned off power management features in the driver properties

-Tried actually making windows recognize the chipset as an atheros AR815X (the same chipset as the e2200 but without the edgy gamer branding and used in a lot of OEM solutions) which didn't have any performance difference (although now I'm currently using the regular e2200 drivers but without the killer networking software bloat)


The only plausible troubleshooting step that I have not been able to take is to plug another computer into my powerline adapter and see if that is the problem as the SSD I ordered for my laptop has not arrived yet and my other laptop's LAN port is broken after an incident a friend had while using it which involved forks (don't ask)

Also I can't just haul my desktop across the house and plug it into the router. I mostly suspect its the nic though since killer stuff is always plagued with problems. If anyone has any ideas or suggestions it would be helpful. Otherwise I'll just buy an intel gigabit nic and call it a day.

Wasted a lot of time on the NIC. If power line is involved it's almost always the problem

I wish I could give you both the best answer but yeah its the adapter. I jumped to conclusions too soon mostly because of killer NICs unsavory reputation. Still, next time I buy a motherboard it's going to have intel gigabit lan (well it will be on an AMD board because I can't waittt for zen to come out and taste that 40% IPC improvement and also we will see AMD finally start to move away from the ye olde PGA package and move to LGA on their desktop CPUs).

Anyways thanks for help and if you will all excuse me I now have to go back to being a dummy and disappear from this website again for maybe another year or two.

I did do that but it didn't help. But I did find out something that did help. I was doing some quick reading while waiting in line at the store today and saw that if both units aren't in the same orientation, it can severely degrade performance and cause intermittent connection issues due to polarization. I plugged the based adapter (which was upside down) into a vertical orientation and voilà! Back up to speed again.

Anyways thanks for the help. ♥
