Wireless signal to shop stopped working

Linksys Wrt54g wireless router
May 18, 2010 at 14:13:29
Specs: Windows Vista
WRT54G & Cisco yagi on roof w/50ft of MR400 wire to send my signal to my shop 300 ft away. Set this up last fall & worked fine till just recently. Now I can get signal in shop at wall closest to house but not on other end where I need it. (stick built shop w/6 rooms) Up on a hill in VERY rural area. Only physical objects are a stand of 7 close together dogwood trees.
I have a WAP54G v2. Can I plug this in at shop to pick up signal? Need to Ethernet laptop to it? Might a wireless N notebook adapter pick up more signal?
Any option other than cutting down the trees?

Set this up last fall & worked fine till just recently.

With a statement like the above, my question is always, what's changed?

I suspect the trees didn't suddenly grow up in between the house and shop in the last 12 months so the problem isn't likely to be them.

Something has changed either in your shop or home, with regard to your wireless. When did you first notice the issue? What, if anything, changed right around that time?

Have you added any more wireless appliances to your home or shop (cordless phone, wireless home theatre speakers etc) that could be causing interference.

If nothing has changed check all connections on all equipment to ensure nothing has come partially unplugged.

The only other thing I can think of is a hardware failure.

Wireless N isn't the solution for your problem, because the higher the transmission rate, the susceptible your wireless connection.
Therefore I would suggest, to switch to wireless A or B and see what happens.

That may well be the answer you your question. Last fall, or autumn where I live, there were no leaves on the tress. It's now well into spring and getting onto summer and there will be plenty of leaves on the trees scattering the radio waves all over the place.

I have no ides what a dogwood tree looks like and how much foliage it is likely to have.

As I wrote in Response #2, try to switch your wireless router to wireless 802.11a or 802.11b.

Sorry but I had to do research to learn enough stuff just to do the install and I dont know how to switch my WRT54G to A or B. And I dont understand what that means.
Can you explain?
I appreciate your time.

Switching to Wireless A or B means, that the wireless network will be slow down to e.g. 11 Megabit/s or 22 Megabit/s.
This mostly results in a more stable wireless network, payed by less transmission rate.

To change the wireless mode, open your web browser and type in:
Login with the username and password.
In the routers administration interface, click at Wireless tab and choose the wireless mode. Default is Mixed.
You can choose Mixed, B-Only and G-Only.
Try the B-Only then click save settings and check, whether the wireless connection is more reliable.

I just reread your initial post and realized, you don't have an antenna at either end. It looks to me like this "yagi" thing is an extender, not an antenna. If so, this could definitely mean the leaves are causing interference.

If this setup ran OK without any leaves on the trees but isn't now that there are leaves, then it could very well be the foliage causing your issue. Did the issue start about the time the leaves came out?

This could be easily fixed by using two antenna's in a point-to-point shot from house to shop.

If you have the extra $$$, you may want to look at buying two SOHO level antenna's and making a direct point-to-point shot from house to shop. One brand name I'm familiar with is "EnGenius". Google them and have a look.

A point-to-point shot like this would negate the trees as being part of the issue.

If however, your setup did run OK with leaves on the trees then please say so now so we can rule that out as an issue

Just an FYI folks, I have a point-to-point wireless shot running between two buildings here in town (about 1/2 mile apart) and there's a hill, thickly covered with trees in between. There's no degradation of signal in the summer after the leaves come out. Mind you, this is enterprise level equipment we're talking about and not mickey mouse SOHO stuff so that could be why.

Also, changing from G or N to A/B won't make any difference.
