Why is my ping so erratic

[Jerochy]

Hey guys,

 

So in short, I built a PC for my GF's house, originally had a powerline connection that would sometimes be awesome, sometimes be horrible. I figured it was the houses wiring as it seemed it would be really bad when the washing machine turned on, so I got a wireless card. I was able to snipe a ASUS PCE N10 on eBay for $3 and it was half decent. Sometimes it would work pretty decently pulling 8MBps with her internet rated at 25MBps. Other times, it would go down to around 50kbps and was awful. I figured it was just pretty cheap. At this point, I was pretty frustrated because it seemed nothing was working, but I knew her internet was pretty good. I've brought my laptop here in the past and never got past 70 ping in games while she was on netflix and whatever. Then I brought my desktop here that has an integrated wireless card and it also wasn't passing 70 ping in games while she was going nuts on her laptop. 

I just wanted something that would work pretty much at any cost at this point, so I went to besbuy and got a "Netgear AC1200 USB wiresless adapter" for $54 dollars. The first night, I had no problems whatsoever; it worked great. I came back a couple days later and it seemed to not be working as well as it was before. I got into WoW and my ping was around 2k, but then after like 10 min of moving the antennae around, it worked fine again. I came back here tonight, and I've been going insane. 

I got on, had really high ping. I tried moving it around for like 20 min with mixed results, and then just unplugged it and replugged it back in. It worked at first, my ping was around 35 for like 15 min while she was on netflix and whatever. Then it started getting bad once again. I unplugged it and put it back in, same thing, worked great for like 15 min and then right back to being bad. 

 

I don't exactly remember what bestbuy's return policy is, but I have all original packaging and receipt and I bought it around 10 days ago. I'm wondering at this point if I should return it and get some other wireless card that will work like my laptop and other desktop does. 

I did install the drivers from the disk it came with and went on the website to install the latest drivers too. I pretty much just don't know what to do and was hoping someone could shed some light on the situation. 

Thanks.

i had the same problem try configuring QoS settings in your router for the ports of the games your wanting to play or turning off wifi multimedia options also in your router

World of warcrafts ports would be 1119 and 3724

I'm thinking it's the card though just because when I brought my desktop and my laptop over, I didn't have any of these problems.

How did you connect your laptop and desktop? Via the same wifi?

 

If you have a smartphone you could try installing wifi analyzer to see if there are overlapping networks on the same channel.

 

How does speedtest do when the ping is high?

 

How about latency with a LAN ping? When you get the issue, try pinging a computer connected to the same wifi?
