Re: My new u310 gives really low speeds on wifi

2014-01-30, 23:37 PM

I found a solution to the problem where you lose wifi signal from lenovo ideapad U410. I went to mydigitallife dot info and downloaded a modified BIOS to remove the whitelist for wireless adapters then I purchased an Intel Centrino Advanced-N 6235 card and installed it. Then I threw away the crap atheros the ultrabook came with. Downloaded drivers from intel support site and done. Now I see wireless networks from 100m away and still connect to them. Also supported by linux, windos 8, vista and xp. Has bluetooth 4 and 300mbps + 5Ghz. I had quite a fight with Lenovo on the phone about this but didn't solve anything. Also I replaced the crap msata ssd with a Crucial 128GB and installed the whole operating system on it. Removed IRST from BIOS, deleted swap and removed hybernation. It's flying. Also works with FN keys to disable it if you want. Cheers and best of luck. Spread the news, Lenovo is not going to do sh*t about it anyways, so better fix it by ourselves.

I just hope they won't delete my post, at least they must have the common sense to let us fix the problem our way if they are not moving a finger for it.

From my experience, the problem is at hardware level with the wifi card. What makes it more difficult to replace it is the BIOS with the whitelist that blocks the instalation of random cards. That's the only reason you need a cracked bios. It will not fix the problem of the wifi by itsef, it will only allow you to replace the crappy one. Problem is, I can't see anywhere what version I used but with a little research you can pull it off.

I have a U310 touch that was manufactured on Aug 2013,

 

I just can't believe I did such mistake in purchasing it. wifi is almost not working at all,

 

And the most unbelivable thing is that they know it from 2012 and still didn't fix it!!!! they just continue to sell new laptops with known issue.

 

600$ spent for nothing.

 

I will never buy Lenovo again. Never.

Try this. Go to device manager. Select the Intel wireless card, advanced and disable the .11n mode. Since my router is only abg ( lower speed). No loss to me. So far this fixed the problem after 2-3 days of frustration, and no help from Lenovo. My guess is lenovo knows the solution but hates to tell people to disable a selling feature. Anyway so far it's fixed my wireless problem when I get more than 20 ft from my router....

Re: My new u310 gives really low speeds on wifi

Hey guys,

 

I am Kostas, new at this forum. I just bought a new U310 Ultrabook and unfortunately it has the same known wifi problems. I did the BIOS mod, and swapped the wifi card with a AR9280 like recommended in one thread here. I also bought some shielding foil. In this thread in this forum you said that your Ultrabook works perfect now with the new wifi card and the additional shielding foil. 

 

Would it be possible that you could show me exactly where I have to put the foil? I do not want to do that wrong. If possible, a picture would be great.

 

If you could help me, it would be more than wonderful. I need my U310 for work urgently.

 

Many thanks and with he best wishes )))

 

Kostas

   Could anyone confirm if this method works?

Post Edited: Tested and method NOT working!

I put double layer of the kitchen foil onto the back cover. 2 separated pieces, one to the WIFI side, one to battery/HDD side. Both good contact to ground fixation screw.

Result: worse WIFI signal.

 

Analyse & conclusion:


This method is in fact a stupid try, because the aluminum foil shield is really redundant, we know the top/bottom cover of U310 is made of solid aluminum panel and they are grounded to main board also.

 

AFAIK, Lenovo said to have solved this issue in July 2012, so models after that should have no issue.

 

Technically, I think the most relevant improvement should come from the antenna, normally the 2 wires from WiFi card should be linked to /along the screen frame, which would be vertically setup, depending on the end fixation and wire shield/thickness/material/length and also maybe the shape it forms, the WiFi signal differs.

 

Not a electrical engineer, or RF specialist. Just share my experience.

Guys,

 

in this post i'm writing that i followed the hint from the page 49 of this forum (post by

And finally my u310 could work with a normal speed of wi-fi card. I have made a modification of a bottom case panel of the laptop. I took an old eeepc, unscrewed back case, took a shielding foil, sliced it in two separate pieces and fixed in the upper corners of the bottom case. It works great, now wi-fi is stable and i have a signal in my kitchen, where no signal previously.

 

Proof, this works

Below is the picture of my modification. And yes, you break a waranty if open.

Also i've change memory from 4GB to 8 Gb by Kingmax, works good. Next stage miodification will be replacement of  a wi-fi module on Intel centrino 6300. But so far, it works perfect with inbox Broadcom adapter.
