Re: New y510p with a wifi problem

2013-08-12, 20:23 PM

It sounds like radio inteference from the 2.4 GHz band. Since Linksys E3200 is a dual band router, try purchasing a dual band USB WiFi adapter like the Asus USB-N53 and connect to the 5 GHz band. You should have much less radio interference at that band and should give you far stable connection and low pings than the 2.4 GHz.

Re: New y510p with a wifi problem

Would you suggest disabling either the 5ghz or the 2.4 on the linksys router ?  

 

Would you suggest going USB over trying to get lenovo to replace  the internal adapter?

I hate to think but you may be correct to say that my solution is to get an additional USB adapter.  

 

I recieved the Laptop less than a week ago. 

 

 

I will run by Best Buy and Pick up a USB dual band just to test and post results.

No. Keep both 5 GHz and 2.4 GHz broadcasting simultaneously and use the 5 GHz when gaming or close to router. The problem is that y510p comes with a 2.4 GHz only WiFi adapter. Lenovo has a whitelist that only allows certain Lenovo FRU internal wifi adapter to be used for y510p. The problem is that it's very hard to find a Lenovo FRU WiFi card on the market. You can temporarily purchase a dual band usb adapter and see if the network lag is fixed by using the 5 GHz. Just make sure when you purchase the dual band usb adapter, it comes with 30 day return policy since you're using it for testing purposes. If the network lag still occurs then use ethernet then it could be router's problem. Also update your router's firmware to the latest. If there's still wireless problems with both the internal wifi adapter and usb dual band adapter after updating the firmware then just play using ethernet where you won't be affected by radio interference and lag.

Very good suggestions. Do you think this adapter would work well with the E3200 ?

It should since both are Linksys products so go ahead and test.

 

One more thing. Just give a different SSID for the 5 GHz band to make sure you're connected at the 5 GHz band.

Re: New y510p with a wifi problem

Purchased a Linksys N600 USB and it connects at a solid 300mbps and works like a charm.  Now I need to decide what to do about the internal adapter ? Is this a defect that I should request a replacement ? Or does the card just suck ?  Or should I try disabling the 5ghz band on my router?

The internal card is the fault. You can try to persuade Lenovo to replace the card with a new one or get a better one based on the Lenovo's approved wifi card list. You don't need to disable the 5 ghz band since we know the USB adapter works with the default router settings while the internal wifi card just loves to drop connection. It's not just your Y510p since this thread has a lot of posts. Lenovo makes great laptops except for their WiFi adapter. Now if they make an FRU version of the Killer Wireless-N 1202 or Ultimate N 6300 for the Y series as the standard, people would be not complaing much about WiFi.

Re: New y510p with a wifi problem

I'm having the same issue with wireless connectivity and have tried all of the aformentioned troubleshooting methods. So if it is still not working after all that my only recourse is to return the laptop? I've only had it for a few days and I really love the machine but there is no way I'm keeping it with a defective wireless card and no way to fix it.

Hey, I had the same issue when I bought my machine and I simply went to the intel site and installed the updated driver. No issues since! 

 

I've attached the link to the AutoDetect site here: http://www.intel.com/p/en_US/support/detect/wireless

 

You may need to hardwire your connection in order to download the update.

I updated to the newest driver and I have to admit that on my first test it does look to be better.  (NOT FIXED) but not as many lag spikes and seems to recover faster.   Another thing I would like to try is to disconnect and reconnect the Antenna from the internal card.  Can someone tell me how to access the internal Wifi card on the y510p.  It seems as if the antenna is weak I notive the winreless N speeds going from 72mbps to 144mbps and I seem to never be able to get a 300mbps even 10 feet from the router.   I started removing the screws on the back to remove the back of laptop but it was very hard to take back off so i stopped just in case i am missing something.
